The water pump & crank pulley line up perfect, I bet the alt pulley is wrong. If I read correctly you said the correct alt pulley would pull the belt forward 1/4" ??

It sits off the fan face about a 1/4".
Here's one for reference on D&R Classics' website,although they didn't come shaded gold from the assembly line back then.

Thanks Rick,

Ill try the repop. I have some old alts laying around. I can get an old fan off of one of them. Is the 1100837 fan different or are they all the same?

I bought a couple of new fans from GM. They aren't quite the same as the original one but don't cost much.

Mr 70

If Alt.pulley #1970831 was a original factory item would it be minus the keyway??????
