Hey,
Dows anybody know offhand the gear ratio specs in a muncie M-22? I can't get a straight answer out of most anybody on the web. I've got the 26 spline "660" case.

 

There is no straighter answer than can be found by going here: https://www.5speeds.com/muncie2.htm

Paul Cangialosi is a master reference when it comes to the M-20/21/22 series of tranny's from Muncie. I believe his company even builds completely new ones, case and all. The bee's knees. He also has some amazing videos on YouTube.
