Chassis work on my 1/35th scale 1937 Available WS series truck. This is a conversion of the ICM Lastkraftwagen, which was a Renault series truck used by the Germans during WWII.
What I've done is make the chassis look more US-like.
Modified the kit cross-members with some C-channel.
The rear axle is from some unknown 1/25th scale car kit. Much beefier looking than the kit rear axle. The truck is supposed to be a 3 ton, after all. I had to modify the engine and radiator mounts as the engine and driveshaft were offset to attach to the rear axle.
At left are the kit tires. They're the proper size in scale, some 7x20", but they just look so anemic. On the right is an AMT 1/25th scale car tire. Much beefier, even if a tad out of scale. The wheels fit the latter nicely.
Making the engine look a little more like a US one. The truck came with Waukehsa engines, but I think that the kit engine looks more like a Continental. But hey, modeling is an impressionistic art, after all. The black are was ground off.
