I like these older Cats. The cabs are neat, with the triangle windows.

That's an interesting drivetrain and frame. So you've got what looks like Axial axles, but you made one with a pass through input/output shaft, and you are using that as the mounts to allow for axle oscillation? That's actually a pretty cool idea. I don't think I would have thought of something like that. How's it work? Just a couple bronze/oilite bushings on the input/output shafts to allow oscillation? Kind of surprised there is enough shaft left to hook up the driveshaft yoke.
