I have a water pump pulley and a crank pulley that I removed from my '67 SS.
I thought they might have been the original smog pulley but a reliable source has confirmed they they are not.
I even tried contacting GM Canada but they were unable to identify these GM part numbers.

I wondering if anyone can help I.D these pulley's:

Water Pump - 3900434AB
Crank - 3874418BS

These numbers are clearly stamped on each item. Both are double row pulley's

Thanks,

Chuck Frame

Thanks Mike!

It was just that easy.... not really sure why GM Canada couldn't I.D them. Maybe it was just a lazy parts guy at the dealer who never bothered to check [img]graemlins/angry.gif[/img]

Thanks Again!
