Ive read most of the posts on this. Ive got a rebuilt TH350 lined up to buy from a local tranny builder. Im planning on buying it with a 9" tail shaft so I should be able to use my drive shaft (91 formula). IM getting the B& M adapter kit which should allow me to use current crossmember and torque arm I think.

Now I guess I need a box that converts the manual speedo signal to an electronic on based on my rear end gearing right?

What about connecting the linkage to the shifter? Can I use the stock one? I was thinking about getting a B& M megashifter but all the ads say it works on 82-92 Camaro Firebirds (except 91-92 Formula) which I have

Any thing Im missing?
