It looks like the frame is different too.
15/16 front fenders.

I have a TT frame that looks like this it is a frame extension that was made by ROWE it makes the frame about 3 feet longer it has 2 leaf springs I think it is 2 ton, it has a bracket that mounts the drive line to the frame and a shaft connects the drive line to the transmission I plan to use it on a truck we are building
Interesting rear wheels. Solid rubber tires and a beefed up center.
