Model Car Garage in their usual fashion includes script emblems for every available model of the car the detail set are for, you also have the emblems for Ranch Wagon, Country Sedan and Country Squire and AMT has never done them in kit form. But the MCG sets can be adapted for other kit makers than stated, I have used a detail set meant for the Revell 55 Chevy on an AMT kit and it worked well with a couple of small modifications.
The "stick-like" thing poking out from the cam cover you are refering to is a cam driven mechanical fuel pump (or fuel pumps if there are two) feeding the fuel injection system. Top Fuel and Funny Car engines doesn't use any water pumps as they don't have any water in them and dry sump oil systems are more used on Pro Stock, Competition Eliminator, NASCAR and that type of engines, but Funny Car engines have a dry sump oil system to be able to mount the engines lower in the chassis without the oil pan getting too close to the ground. Here are a couple of pictures on Hilborn FI systems.
A while ago I showed my new car but it wasn't really as I wanted it, I got the wheels and tires I have been waiting for yesterday and mounted them today, now I'm satisfied with the stance and how it looks.
As far as I know they only raced the Mk IV at only two races in 1967, Le Mans and Sebring, and only 6 cars were built, 1968 and 69 they went back to the Mk I as the rules were changed to maximum 5 litre engines and Ford themselves got out as a factory team.
The small tires for the front wheels on drag racing cars are called "Front Runners" and they are specially made for racing purposes. Several Revell, Monogram and MPC drag racing kits have front runners but they can also be found on the aftermarket.
The only kit I have ever given up on is this one. It's a modified reissue of the Orange Crate kit and if the Crate is difficult this one is even worse as it doesn't build up the same way...well some things are but other things doesn't. I bought it back in the 70's and I thought it looked cool but it was unbuildable at my age, I think I was 13-14 years old at the time, I've got one more (and a couple of the Crate's) and will give it another go when I feel up to the challenge.
Okay...but the holes are not that large between the spokes as you can see at the picture below so I don't know if they will show that much on a model. Painting techniques...the 63-64 wheels are bare with polished spoke and rim edges and the cone and spinner are chrome, so I don't know but I would probably paint between the spokes with aluminum paint and wipe the edges off. The 65-66 wheels are darker between the spokes so I would use a darker grey color for them.
You can buy HRM stuff through Replicas & Miniatures Co of Maryland, Harold Bradford from HRM and Norm Veber from R&MCoMd are friends and and both live in Maryland, and I have bought HRM stuff from Norm before. Strada Sports and Island Collectibles also usually carry the HRM stuff. But Harolds wheels are 1:24th scale and would be a bit too large for a 1:25th scale model, 15.5-16" instead of thje standard 15".
@Raoul: The kit wheels look a lot better with the 62 Impala spinners.
Nice, I built that one a long time ago back in the late 80's and I still have one more in my stash. Wich version are they?, the rarest are the first issue with Air Ride, the later ones had Walking Beam.
