I found this original 2 groove waterpump pulley p/n 481040XT D in a tote of parts with the '72 Buick 455 engine I bought recently. I thought maybe some loyal Buick guys may also have a Pontiac. Its supposed to fit all '71-'75 engines w/AC. A,B,F, and G bodies. Part is located in Iowa. $20.00 plus shipping.
