Anyone have a picture of the correct crank pulley for a 71? I think they are all the same for our trucks Chevy & GMC? This is what I have and I’m having alignment problems.

Weren't some of the originals two stamped pieces (seperate pulleys) that were stacked together? Is that pulley in your pic cast? I had a cast one that I sold to another member (turned out later that it was cracked

) it had come off an engine that had an early aftermarket underdash A/C system.

that's why I think it's not correct. I was looking in a catalog and the only cast unit was for a BB? I think this might be my problem.
