I've got an 87 XR7 with 3.73s and an aod. I'm using a 21 tooth speedo driven gear and have been told that I must have the 8 tooth drive gear. I will be removing the tranny tailstock to replace the output shaft bushing and was wondering if it was possible to change to the 7 tooth drive gear while I have it apart. If so what is involved?
:canada:
AAAAhhhhh, I see.
Now that I've got it apart, I understand that the gear is a permanent fixture. I'll be getting a 23 tooth soon i guess.
