  1. Sorry for the slow response guys, been busy with the baby for a bit. As Brian said, the cab fans are 3D printed.
  2. While I agree to some extent, it may make it even more confusing for some. Most of the model truck kits (AMT kits at least) come with older tube-type rims. These had a deeper lip, and were 20" or 22" when measured at the tire bead. For this reason, AMT tires are stamped as 20" or 22" on the sidewalls. In real life, when the switch to tubeless tires occurred, the lip on the rim became shorter, making a 22.5" tubless wheel equivalent to a 20" tube type, and a 24.5" tubeless wheel equivalent to a 22" tube type. In general, a 20" tube-type rim and a 22.5" tubeless rim will have an OD of approximately 24.5" while a 22" tube-type and a 24.5" tubeless rim will have an OD of approximately 26.5". The problem lies in that many people do not know the difference between tube-type and tubeless rims. Since many people want to use kit tires on aftermarket rims, many aftermarket manufacturers try to list the rim size to match the kit tire nomenclature, so they may call a 24.5" tubless rim a "22 inch rim" so that people know that AMT's 22" tires will fit on it.
  3. As mentioned, the real truck had 24.5" rims. This measurement is taken at the bead of the tire, so the actual outside diameter of a real rim will be larger than 22.5 or 24.5 inches respectively. The aftermarket rims from Moluminum are perfectly in scale, he offers both 22.5" and 24.5" rims. Doug Wagner also offers machined aluminum 24.5" rims in 1/25 scale that are perfectly to scale. If you want the most accurate looking build to the real thing, I would say use Doug's aluminum wheels. It is an expensive option, but it is the most accurate way to go. Moluminum's resin wheels would be my next choice.
  4. I was finally able to get some outdoor shots.
  5. Class A resins was Ben Wicker selling parts made by Jamie Rahmoeller. Ben is done selling parts, but you can buy Jamies parts directly from him now at http://moluminum.com/.
  6. The torsion bar suspension continued to be popular into the early 80's. It took a couple years for the AG100 to become popular. That is the first time that I have heard that the Peterbilt air leaf suspension was a factory option from Kenworth back then. KW had its own 4-bag air ride suspension in the 70's, but it was different from the Peterbilt suspension at the time.
  7. This was a common upgrade for Kenworths that had torsion bar suspensions back in the day. From what I hear. it was easier to replace the torsion bar setup with a Peterbilt air leaf setup than to try to swap on the KW 8-bag air ride suspension. I have seen quite a few KW's that have been swapped from torsion bar to Peterbilt air leaf suspension.
  8. Thank you. I made those out of .030" square styrene rod. They are quite simple to make, but they help improve the look of the model over the molded in wipers.
  9. Rivets, rivets, rivets. Not perfect, but at least there is an essence of rivets on the cab now.
  10. Most of those Dodge NCT-1000's that I have seen have had Cummins diesels mounted at an angle as the drawing depicts.
  11. Thanks Hermann, your builds are definitely an inspiration. Hopefully I can make something close to yours. I did widen the cab by 4 inches. I am going to use a 3D printed grille that I designed to be the correct width. I think I am going to use archer rivets, but I may try some other options on a some scrap pieces first to see if something else will work better for me.
  12. Thanks! Yes I did move the headlights down. I probably should have moved them down a hair more, but then I would be into the heater vent intake on the passenger's side. On the 1:1 the right headlight is about 1" above the heater vent intake, but I don't know how accurate the intake is on the model. The headlight position will have to do for now.
