Could you please give me the diameter and lenght of the two interlock pins?
I rebuild my tranny and find out that no interlock pin is there.
I check on David Kee site but can't tell which one it should be. The tranny is from a '73 Mexican Sprint Mach 1, and when I look the rail kit it's not the 71/73 one I have, but 69 or 70, rail kit 4 or 5.
Shift Rail ID
Not uncommon for Mexican built Mustangs to use left over stuff from previous years. They were not built to meet the U.S. specifications or market.
I will look today to see if I still have a set of 69/70 rails and detents.
It would help me ID the detents that you need if you can post a photo of what you already have.
