A couple of A-body rookie questions.
I have been through all this with my 64 Dart project
Brewers sells pretty much everything you need to convert to the 10.5 clutch. You will need their fork, fork pivot
pivot points, clutch adjustment rod kit.
TS 636 Torque arm
BSB 636 Pivot mount that goes on the BH ** See below
FP 484 Fork Pivot
CF 702 Fork
AK 636 Clutch adjustment kit
** The BSB 636 will only work with the following bell housing castings
2843887
2892482
3515734
I ended up modifying a 67-70 bracket part number BSB 482. I couldn't get the holes on the bracket to line up to the bell housing

Give Brewers a call
Good luck
