M-code A-body question

Fortunately the kick down linkage was on the car when I bought it. I would like to find an 093 727 for it one day, although I rebuilt the mid 70s trans that is in it and I like how it shifts. Also before I bought it, somebody had pirated the 3.55 Sure Grip out of it and put some 2.76 open gears in it. I have built some 3.55s with a Tru-Trac locker which will go in this spring. It clips along with the 2.76s but the 3.55s will be a big difference.
