Get a hold of FirebirdBill (Bill Edmunds) at: EarlyBrds@aol.com he might have the pulley you are looking for. Another option is watch eBay. I've seen a lot of Pontiac pulley's in there. There are a lot of parts that are listed for "GTO's" but they will work on the Firebird's. Just make sure all the dimensions add up. The sellers list them that way because they can list them for a higher price. I bought a "1968 GTO power steering pump assembly" from a guy that sells Pontiac parts and come to find out it really came off a '68 Firebird. Also, don't ask the seller if it is a 5-11/16" diameter pulley. Ask instead, what the diameter, depth, and bolt circle, etc. of the pulley is. Sometimes they will tell you what you want to hear. Hope that helps.
