Hey guys, new to the site and looking for some help. I have a 68 4 speed car. I recently bought a Muncie m20 that was claimed to be rebuilt which I now believe is untrue. Aside from that when I put in the new transmission I also replaced the clutch. The TO bearing is 1 1/4" long and I though I read somewhere that the pontiac bearing is 1 13/16" if I remember right. I have the TO bearing all the way tight to the pressure plate fingers and still can barely get the clutch to disengage. Could it be the TO bearing,, clutch fork, or maybe z bar? I'm at a loss here. The car has a 68 gto 400 in it so who's to know what else may not be true to the car. Any suggestions on what to check would be greatly appreciated. Thanks alot
