I'm sure I need a new speedo gear since the old 8.75 was 3.23. 23 spline 4spd matted to a 383 FYI. Do they make those reproduction in various teeth count to chose from? Who sells them? I also increased the tire diameter a little. I had on there 215-70-14s and now have G70 redlines. The overall diameter change isn't dramatic (maybe an inch or so), but would that also have to be compensated for and if so, how? Thanks!
