need help with 3 speed transmission mount and driveshaft

[Mark B]

I have a 3 on the tree and 250 six in a SWB leaf spring truck.

Does anyone know how or if the tranny is supposed to be mounted to the frame? Right now it is unsupported.

This is a shortened LWB truck. The orginal truck had a 2 piece driveshaft with a crossmember that supported the end of the first shaft back from the tranny. It has a single shaft now, and that crossmember has been partially cut away to make clearance for the driveshaft. The crossmember doesn't support anything at all now. The only drivetrain support are the engine mounts, and I think that is causing some drivability problems.

Any pictures of how this should look would be great.

thanks
Mark
