The TH350 did not have the holes in the tail shaft housing.. someone must have installed one from a700r4 I hear swapping the housing will cause proplems... B&M and others have a steel bracket for your TH350 conversion
the TH350 must be a short tail from a pick up truck...

Re: 700r4 to a 350 turbo

I had a th350 in mine. With that tail shaft, you will need the following to make it work. A longer driveshaft because that trans with that tailshaft is shorter that the 700r4, a different crossmember or modify yours because the mount does not line up properly, a bracket kit from b&m or hurst to bolt up the torque arm. Hope that helps you.
