Found my original radiator but decided to go with an aluminum unit. This is the stock Harrison copper/brass radiator, part number correct “UPâ€code unit for 68 Firebird V8 with A/C. This is the HD 4 core version and worked great before removed 7 years ago with no leaks. Car has always been in California. The correct tanks are in great shape and have “ONâ€(pass.side) and “IL' (driver's side) stamped on them. I’ll probably regret selling, but I need to clean out the garage. I need to have $950 plus shipping for it, PayPal OK.
