I just picked up an M-21 rockcrusher for my 82' Z28. Does anyone know how to mount it to the crossmember because its about 4 inches too short? Or is there a company that makes a crossmember for doing this? I've also heard that 82-84' could come with a 4sp muncie, would that crossmember work?

 

FYI, M21's were NOT rockcrushers



M22's were

its going to be a challenge i can say that

 

whats an m-21?

 

woops, i don't really know to much about it i was just told that it could handle the torque that my engine is going to be producing, and i had picked up a parts car that had a 350 block and the M-21 in it so i figured why not. I have everything taken care off except the mounting of the panhard bar and the crossmember but it looks like I"m just going to have to make something totally custom for this one. thanks anyway

 

an M21 is an M21 is an M21


the M22's knickname is the rockcrusher


its still a decent tranny

 

yea worse comes to worse i could just set it up for the m-21 and if i run across an M-22 i'll just swap it in
