My 81 was originally a 4 speed and the previous owner converted it to an automatic. It presently has a th350C in it but I plan to replace it with a regular th350. The speedo is way off and I need to know what gears need to be in it to correct the speedo. Anyone know the colors or number of teeth I need or know where I can find a gear calculator? As far as I know the differential is the factory 4 speed.

I checked the site out and I need to know either the drive gear size to find the driven gear size or the driven gear size to find the drive gear size. I don't know either size. I need to know what came in the 81 so I can replace both gears.
