For reasons unknown, this pulley came on the 73 Camaro Z28 that I recently purchased. This was the only deep groove pulley on the car. The car is supposed to (and now does) have all shallow groove pulleys, so this is up for sale. I've looked at pictures of like pulleys that have been sold here previously and, as far as I can tell, this is an original GM item, not a reproduction as are currently available. Back side may still have original semi-gloss black paint but front side has been painted with 'cast blast' or 'bare steel' type grey paint. It ran nice and true when it was on the car. See pictures for details. $250 includes shipping in the USA. PM here, email
