I found this chart on the web and thought it would be good for use by all of us that have and are going to change our diff. gear. The driven speedo gear you need to have with respect to the ratio you used in the rear, you might also have to take into account the tire diameter too. I'm not going to bother with that though, because it is likely to end up in-between gears.
AOD with 7 tooth drive gear.
Rear Ration / Tooth Count
2.73---16 teeth or 17 teeth (getting mixed messages on this one)
3.08---18 teeth
3.27---19 teeth
3.55---20 teeth
3.73---21 teeth
4.10---23 teeth
AOD with 8 tooth drive gear.

The 7 tooth drive gear AOD is the older one so most of the AODs that we have are that, but it would be a good idea to check and see what you have for sure. Now that you know what you need, here is where I found to get it so far. They use frames on their wed site, so I can’t link to it right, but this is the page you need. The second one sells the 17 teeth one.

Thought this was pretty cool to know, so there it is.
