I was just looking at a set just like that yesterday on Amazon. I might be able to work something out with a printed grill/radiator assembly for the front mount.This is a very interesting project, you are working on. The last couple of months I've been thinking to do a TRX-4 to TRX-6 conversion using one of the kits as base platform. I really like your cantilever setup.
Have you consider getting those paired magnet mounts?

If you have enough space between the battery box and the body, one pair could go there and another behind the front grill and a printed base on the chassis. Just a thought.
I'm thinking once the front end plate is installed on the bed, if I glue some magnets to the outside (between the bed and cab) I could probably hide matching magnets on the inside of the cab. That way the back of the cab is held by the bed and the front by magnets fixed to the front of the frame.
My other thought was reprinting the floor plates with a recessed hole added for magnets, then glueing a steel plate to the underside of the running boards.
