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?
