1966 Tranny Mount

[taz9180]

Hey guys I have a 1966 Power Wagon w200 4x4. Came originally with a 318 4 speed. I'm putting in a 383 magnum with a 727 TF and a new process 203. I'm having trouble finding a Transmission mount. Will the cross over mount off a newer truck work or do I need to try and make my own? Any help would be great
