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.

Your're welcome.

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.

Looks good.

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 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.

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. 😉

The pictures are gone.

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.

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.
