I don't know that you'll be able to see in the hole where the speedo cable goes in to count the drive gear while in the car. Even out of the car it would be a bit tricky.
I have a C4 mated to a diff with 3:70 gears in a Triumph TR6. KAR mustang parts in Columbus, Ohio had the correct speedo gear, reads spot on much to my surprise. The car is offsite in storage presently, otherwise I could probably find the part # in the book that is in the trunk. I seem to remember different speedo gears are different colors, but it's been 10 years since I built that one, and cannot remember. Gearing is too high numerically, shifts almost immediately and revs are up around 2800 at 60mph. I'd like to change to something like 3:50 gear, but choices are limited with the TR6 rear diff.
