M20 drive gear
#2
When I was looking for a speedo gear I reached out to Autogear, told them all the specs (tranny type, rear end ratio, tire size) and they sent me the correct speedo gear. It's within 2 mph @ 60 mph

I know there are also calculators on line to figure it out yourself

He's got some great rebuilding videos as well. I need a rebuild kit for my Mustang's T5 but unfortunately he's out of stock and apparently has been for a couple years. Maybe he's sticking to Muncie's and T56's now

There is a speedo gear chart on TCI page that will help determine what gear you need. You need to know the tire diameter, and either the drive or driven gear tooth count. Enter those figures, it will calculate the other needed gear.

Well, crap. It just occurred to me your working with a manual trans. TCI doesn’t list gears for a M20. The formula would be the same, so you determine the correct needed gear. I’m not sure if the gears are the same between auto and manual trans.
