This is some more of the underside. The brass shim pads are a wear surface for truck bolsters to sit on, they are 0.015" thick. These will be glued to the location shown.
This is the development of the number board for each end, note three are narrow and three slightly wider.

The cabs have been interesting and I've made several construction alterations and now I'm doing more as I want to ultimately end up with a unibody for rigidity and better support of the frame.
Here I've opened up the ends of the cab walls to accommodate guides I'm putting on the ends of the hoods. This will allow the hoods to be installed and then the cab assembly to slide into position and lock all three main components together.
More to come,
