Chris,
I used the T400 adapter kit by Hurst. (B&M also makes one) It was ~$125 from Jegs.
For the drive shaft, I had an old shaft from a Chevelle that I had cut and balanced (~$90). Spicer makes an adapter u-joint for the rear. You can also have places like Clutch & U-joint (it's actually called something else now) make you a complete shaft or also
www.dennysdriveshaft.com has good pieces.
I have the exact length somewhere, but I would install the tranny, then measure just to be safe. I will look for the length this weekend if you really want it.
Miles
