No, they are different. You may be able to get a 67-up one to work, not sure. If you need a 63-66 manual pedal assembly, let me know, I may have a good one.
I have a good lead on a manual tranny locally for a very good price. Everything I need to convert except the pedals. So I may very well take you up on that offer. I dont even care if theyre in less than perfect condition, so long as they are hard parts complete. Rebuilding things like that is half the fun.
