US Car Tool K Frame Installer

I made my own out of some 2x4 c-channel I had laying around, and some casters. I treid using uprights into the holes in the k-member, but the motor mounts(older biscuit style) where flexing so I laid the kmember on the cart on some 4x6 wood, the only problem i ran into was the piece of wood the tailshaft was sitting on hit the transmission tunnel so I had to move the wood.
