I am taking the crap 70R4 out and was going to use a TH350 6" with shift kit and use the tailstock from the 700R4 and put it on the TH350 to hok up that dumb torque arm. Is this the right one I have to use (6") ? Anyone who has done this and could pass on the info.. would be great.. thanx


I'm not sure if the tail housings will interchange, when I did this many years ago I used a B&M kit to connect the torque arm. I think the kit is no longer available. It was a steel bracket that bolted on the same bolts that hold on the tail housing and held the torque arm mount.

Or get a rebuilt 700R4 from someone who knows what their doing and will put a guarantee on it.

Thank You, Randy
