Just doing some quick searching it looks like the Hendrickson CONNEX Unitized Air Suspension System is the closest match I've found so far to sort out the axle questions. Not sure if it's been modeled in scale by anyone but shouldn't be too bad to do for a 3D print.
I don't know the make on the suspension they use...but they looks kind of like Neway or something similar.

No problem.
The axles are low mount air ride axles and I have found a few pictures of the underside of a Featherlite trailer.

There are some and here is what I have found out during my researches on the subject as I have plans to do one myself.
The modern Featherlite trailers are 53-53.6 feet long, 102 inches wide and 13.6 inches total hight with a 31-37 inch drop, axle spread 10.1 feet.
Wheels are often low profile 255/70R-22.5.
Some measurements can vary as all trailers are cutom made as you can get them as you wish, but these are the most common ones.
Here is a couple of drawings I found of a Featherlite trailer, you can use them as a guide.

Looks nice for your first truck build, but it would look even better if the rear wheels was mounted as they should be.
Here is how they should look, quite a noticable difference.
The lip on the wheels goes inside the tires...like this.
This is not an uncommon thing and many don't think about it and mount the wheels from the front as on most kits...but that's not the case on the Revell US snap kits.
Don't get me wrong, it's just a friendly tip to make even better models in the future.-

I have a couple of these KFS "Yellow Engines" in my stash.

Nice.
I see you changed the engine to the Cat 3406 A block from the Revell Peterbilt 359 and Kenworth W900 snap kits.
The kit has a Detroit Diesel Series 60 originally...and the tooling still belongs to and the kits are still made by Italeri, Round 2 just bought batches of the kits and reboxed them under the AMT brand. -

I am going to buy it because of the Shelby 10 Spokes
I believe those 10 spokes are in the last issues of the old 1966 Mustang HT and they are in the recently issued 1966 Fastback wich was based on the HT and this kit is based on.
I might get the Shelby myself, but not for that reason.

One personal example, both kits listed as 1/25 scale. I was taking the chassis and drive train from the Revell Hemi Dart and putting it under the old MPC '69 Barracuda. I had to trim about 1/4" out of the wheel base and I think it had to be narrowed too. Should have been a drop in.
16 hours ago, Can-Con said:'69 Dart wheelbase is 111", '69 Barracuda wheelbase is 108". Not exactly a "drop in".
About 1/8" difference in 1/25 scale.

Dodge tends to be a slightly longer wheelbase compared to its Plymouth cousin. This applies all across the Mopar line
Yes you can't compare Dodge and Plymouth that way as Dodge tends to have a slightly longer wheelbase than Plymouth.
Some examples are the Dart/Barracuda A-body, 3 inches difference and the Dart is longer, Challenger/'Cuda, same E-body platform but the Challenger has 2 inch longer wheelbase, the B-body Dodge Charger and Plymouth GTX/Roadrunner has a difference in wheelbase of 1 inch and the Charger is longer.Likewise for Ford and Mercury, the Mercury Cougar has longer wheelbase than the Ford Mustang even tho' they share the platform, difference 3 inches.

I agree, if we didn't have the old AMT kits we wouldn't have anything at all.
The truck model market is too narrow for Round 2 to retool all old truck kits and still make money of them, keep in mind that many of them were developed and first issued in the early 70's (first AMT truck kit was the Peterbilt 359 California Hauler in 1969) so I'm affraid we have to work with what we have.
Round 2 did retool one tho', it was a truck kit where the tooling was modified to another kit and it couldn't be done anymore.
This kit is the International CO4070A originally done by ERTL back in 1973, so Round 2 back engineered the kit from an old original kit, did some modifying to get it even better and issued a totally new tooling kit of that truck in 2021 and it's very nice.
The original CO4070A tool was modified to the International Transtar II CO4070B in 1976 and that tool wasn't among the tooling Round 2 got when they bought the plastic kit tooling from Tomy who still owns the ERTL brand, so it might still be with them, it has to be around somewhere because AMT/ERTL issued that kit as late as 1996.Well back to the original programming. 😉

That’s very interesting. I can’t imagine putting it together with torsion bars. Good grief!
Yes it's quite complicated, here is how it goes together if you have the AMT original kits.
There are torsion bar sets on the aftermarket and they are based on the original AMT parts, but the suspension mounts for the axles are allready attached to the axles and makes it a bit easier to do.
This is one set from Auslowe.

Wow really? I’d love to see it! I’ve always built models but just recently got into big rigs. I never knew these kits were so old until I got on here and started working on them
The AMT Kenworth W925 (and the K123) was first issued back in 1971, so it was quite old when I built mine back in 1979-ish (Matchbox era), I don't have any pictures of it tho'.
The early issues of the kits had torsion bar rear suspension but it was changed after a while, most likely for the second run of the kits, it was changed to the walking beam they still have today.
So if you think the walking beam and axles were fiddly to put together you should try the torsion bars, they were really fiddly so that's why they changed.
A fun thing is that the W925 had the correct suspension when the kit first came out with the torsion bar suspension as the chassis designation *25 stands for torsion bars, so now when the suspension is changed to walking beam it should have W923 chassis designation.
The K123 had wrong chassis designation when it first came out as it also had torsion bar suspension and should have been K125, but it's correct now as the *23 chassis designation is for most all dual drive suspensions including air ride except the heavy spec walking beam and 6 rod wich were *24, and the torsion bars *25.
The *21 was single drive and *22 was single drive with push or tag axle regardless of suspension type.
Look forward to follow your build.-

Thank You! I believe the AMT cummins has a unit similar. Think that could be made to work?
Yes it's the same kind of aftercooler and can maybe be modified to look like a Cat unit.
-
Don't worry Brenton, I will be 61 soon and I built one when I was a teenager and didn't have any big troubles with mine as far as I can recall.
It was the Movin' On version and I still have it on my shelf. -

Good Info to have. Thank You. Did they offer an Aftercooled A block? The #D printed Cab I'm going to be using Using I'm guessing is roughly the era of the A block. Could I add an Aftercooler to the Revell engine or would it be too much work? Where would I source one? This seems like I've gone down quite the Rabbit hole.
Yes the 3406A was available with a water to air aftercooler and had an output of 425 HP.
And yes you can add an aftercooler to the Revell engine, take off the intake manifold and replace it with...well the problem is that I don't think anyone on the aftermarket does a water to air aftercooler for the Cat 3406, it looks the same for the B block by the way.Here is how it looks on the A block.
-
When it comes to the Cat engine it depends on wich era it is, the 3406 in the Revell snap kits are an A block wich came 1973 and was made up to 1986 and was replaced with the B block 1987.
The B block has the injection pump in the middle of the engine block lengthwise and the B anc C has it right at the front cover and a larger cone in front of it and the air compressor was mounted further up, otherwise they look pretty much the same.
Another thing, the Revell engines doesn't have an aftercooler so it's a lower HP engine, the ones with aftercooler had up to 425 HP. -

Nice build of the old ERTL trailer...because that's what it originally is.
AMT had Fruehauf, Trailmobile, Loadcraft, Haulaway and Wilson trailers, no Great Dane wich were ERTL trailers.-

Not a very exciting month, I have unbuilt kits of te ones I like in my stash already...several of them.

The KTA 19 is a huge engine as it's both long and tall, 19 litres displacement and up to 600 hp.
And as Steve say, it's not that easy to get it to fit in the White-Freightliner kit. -

Tariffs are based on suppliers cost NOT retail pricing so yes unfortunately we will likely see a increase in prices but not 145% of retail price
Yes you will see an increase in price, the import tariffs falls on the importer/retailer who have to pay the tariff on their prices from the manufacturer in China or from whatever country they get the stuff from that Trump has put tariffs on, and the importer/retailer will forward their increased cost to the end customer who have to pay more for the product...that's how it works.

Just type in White Freightliner WFA or Freightliner FLA on google or any other search engine and you will get lots of pictures.
The engine in the White-Freightliner kits is a Cummins NHC 250, a naturally aspirated Cummins 855 cui engine, transmission is a Fuller Roadranger.
Here you can find some of the information you need on the engine, this is not exactly the same but it's a Cummins 855 cui engine and most of it is pretty much the same except for the turbo and aftercooler wich the NHC 250 doesn't have.

https://public.fotki.com/modeltrucks25thscale/model_magazine_articles/car_modeller/cm03_sept_1990_truc/
The White Freightliner has wedge brakes tho' and they are slightly different than the more modern S-cam brakes.
Here is a search on this forum on brake systems and you can learn a bit there.
Browse around on the modeltrucks25 fotki albums and you will get lots of information there, lots of instructions and other useful information.

Boss 429 Mustang
in Model Building Questions and Answers
Posted · Edited by Force
Revell/Monogram took some liberty when the designed the engine bay and the shock/spring towers on the model kits.
Here is how the real Boss 429 tower to the left looks like compared with the stock Mustang tower to the right.
