Dave, don't forget that a "700" trans will require a driveshaft shortening, and IIRC, a x-member modification.
If you're looking for an O/D trans, the "200" is the one you want....you can use your stock driveshaft, and there should already be holes in the frame to move the x-member back a few inches to bolt it in.
I think I'm having deja vu.
