Has anyone out there done a swap from a 700r4 to a 400 turbo, if so, did you run into any problems with the floor boards? what did you have to do with the crossmember, torque arm, and driveshaft?

 

I can tell you that B&M makes a bracket for the toqure arm, bolts to the tail housing, and it costs about 90.00

 

The TH400 will fit under the car no problem. Just to make life easier I went with the Spohn crossmember and torque arm for my swap. The driveshaft on mine was the right length (car came with a 200c trans.), just needed to put a TH400 slip yoke on it and have it balanced. Probably the best way to get the right driveshaft length is to get the transmission in the car and measure.
