This is a brand New heater core for 1963, 1964, & 1965 Buick Riviera models with air conditioning AND without air conditioning. The 63-65 Riviera models use the same heater core for both air conditioned and non air conditioned models. This is a very nice heater core. This is a copper brass construction heater core. This is a direct fit heater core (by this I mean it fits in the original brackets with out any modifications). These copper brass versions are very hard to find. The inlet is 5/8" and the outlet is 3/4".
