If you really have a 200 in your car (unlikely but not impossible) then it's already the one you need.

I went from a 700r4 to a TH350 in my 86 and used the same cross member. I used a 9" tailshaft TH350 and the torque arm mount from B&M and that was it.

I use the exact same crossmember too, but I use a kit that adapts the 700r4 tailshaft to my th350. The mount is in the same place.

The 200-4R mount is further back than the mount on a TH350. In fact, it's in the same place as a TH400.

The 200-4R is the same length as a 200-C and TH350 - short tail.

I'm in the middle of my swap, but my stock 82 crossmember for a T-10 4 sp worked, and is the same as the stock 82 crossmember for a 200C tranny.
