I asked years ago about changing the gear ratio in our '67 and was told not to tackle it myself. I just put a Lock-Right in the 10 bolt and got to thinking, how hard could it be? I'm very familiar with dial indicators and Prussian Blue. Is there a good tutorial on replacing the ring and pinion? I would really like to put taller gears in this thing. Thanks.

This web site, and this link, are all You'll need.
