i have a m 21 in mine. i love it. way more fun.

its the more hi perf version isnt it and whats the differance between a m21 and a rock crusher.

M20 Wide ratio standard duty
M21 Close ratio standard duty
M22 Close ratio heavy duty

The parts mix and match quite a bit and you really need to pull the cover off and look at the gears to see what you have. The M22 has a different angle on the gears that cause the distinctive sound. Even with the different angle its hard to see the difference if you don't know what your looking at.

I have had all three in my car at various times. I ran a Richmond 5 speed for many years. They are way more fun but hard on parts at the race track. I switched to an auto more for racing. A street car needs a stick.

i love my m-21 but thought about switching to an m-22 to handle the torque of the big block im building. hopefully the m-21 can handle 650 lbs of torque.

i found out that a guy i know is selling the bell housing, muncie, hurst competition plus shifter which is around $300 its self, pedals and linkage he said its all mying for 500 watcha think.

id say buy it. it wont cost much to rebuild the shifter and the trans itself. just inspect everything and clean it up.

Banging gears is fun! Just make sure you find 'em, don't grind 'em!
