Yes, both chrome trees are different between the Super Boss and the Bandag Bandit so you need the right ones to do the Bandit. If you are lucky there are sometimes parts from the Malone trucks on ebay from time to time...I have seen chrome trees from both the Super Boss and Bandag Bandit there but not right now.
You are not far off there Dave. The Pro Stock cars evolved away from the production cars about that time, after that only parts of the body shell was from a production car and today the Pro Stock bodies are very far away from the production cars, they are longer, narrower and lower and the shape is altered so they are completely different from the road going cars they are supposed to be.
These AFB's are the best I have seen so far. Unfortunately the kit manufacturers doesn't provide good carburetor detailing with a few exceptions, and mostly that's okay for models where the carburetor is covered by an aircleaner, but for models with exposed carbs we need better ones than what's available in the kits. I agree with the request of the Holley 4150 series carbs with the LeMans float bowls, we really need these for several subjects, as well as good high detail Holley 4160 series carbs for the 68 Hemi Dart's and Barracuda's.
You can find lots of pictures of Tyrone Malone's trucks here: https://www.facebook.com/Tyrone-Malone-and-the-Bandag-diesel-racing-team-189062841121878/ And Here: http://public.fotki.com/superboss1/tyrone_malone/ They the best places to find reference photos of Malone's trucks, both sites are from the same man, Ken Harris, who worked for Malone and drove the Papa Truck transporter in the European Tour back in 1989.
Just keep in mind that there has been four versions of the Super Boss with slightly different paint schemes, The first Thermo King version from 1974-78, the first Bandag version from 1979-88, the later Bandag version from 1989 and forward and finally the latest version as the truck was repainted again by the current owner Gary Ries, the decals supplied in the kit are for the first and second versions up to 1988. Here are a couple of engine pics from those sites.
Yes the Super Boss and the Bandag Bandit has rear torsion bar suspension and the model kits are quite accurate as Brian said, the door handles was changed to paddle latch 1972 and the vent windows got smaller at the same time so they are correct for the Super Boss as it's supposed to be a 1974. The Bandag Bandit wich is a 1978 model today has an older cab with the older style door handles and larger vent windows as the truck was damaged in a fire at Malones shop, before the fire it had the later cab and a different interrior. The Super Boss as well as the Bandag Bandit was ordered as "glider kits" with frame, front axle, hood and cab, the rest was put together by Malone and his crew.
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.
