1970 k20 4x4 clutch linkage question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My z bar appears to be too far forward on the engine. Am I missing a bracket? My 2wd has a bracket and this 4wd only has a ball stud?

Thanks!

The engine sits back closer to the firewall on a 4wd, so the z-bar stud is farther forward and just screws directly into the forward hole.

Hard to tell from the photos but, I agree. Something doesn't look right. The z-bar should be perpendicular to the frame and the engine.

Take a look at this thread:
