Rock Crusher identity
It tells how to pick out what is what but the main thing to look for in a M-22 is the gear angle. Take off the side cover and look at the angle of the gears. M-20, m-21 will have 45 degrees gears and the m-22 is 22.5 degrees. They used this to reduce friction and in turn gave it a nice greary noise thus the rock crusher. Chris

A 833 vs Toploader vs Muncie (rockcrusher)
I started out with Pontiacs in the late '70s, and moved into Mopars because of chronic 4-speed transmission problems. I make no excuses about being a big A833 fan, and in my opinion the 18-spline hemi 4-speed is the strongest of the three. The Toploader would be a reasonbly close second, and the Muncie would be the last.
