Need help on the Chevelle

[MuffHugger]

Does anybody have a diagram or anything for the shift linkage on a Muncie M20 4 speed? I have 3 shift rods and I think I am missing one. Any help is appreciated. My dad wants to have this nightmare on the street before August 7th.

3 is fine - its been a while sine ive taken apart a "rock-crusher" but i think its one for 1st/2nd another for 3rd/4th and a seperate one for reverse - they are pretty simple to take apart and put together - there's prolly a total of 15 parts all together. good luck!

3 rods sounds right. It's been awhile, but I made up the rods for my buddy's 4 speed in his '69 Chevelle and I remember only 3.

the rock crusher has 3 rods.
1 for 1/2
1 for 3/4
1 for reverse

got one in a 57 belair.

Perhaps this helps...

why does everybody keep saying rock crusher? the M-22 was the rock crusher, not the M-20....

Thank you.

I know that the longest one is the 1-2, the middle one is the 3-4, and from what I've seen it looks like there is 2 rods for reverse. I'll get pictures of what I have.

I misread, thought it said M22 not M20.

they are the same damn set up though -the only deiiference is shaft size i think, and a case is a little stronger - and i only refferenced it because ive only worked on the m22 and not m20s - sorry i put everyone down the wrong path

Where can I find a used rockcrusher? I just need an M22.
