SOLD. I have in my parts box the heater core from my 1972 GS. It is copper/brass. It has no leaks at least when I put air into it. I removed it many years ago, while the motor was out of the engine bay, not because it leaked but thought it was a good time to replace it. I will gladly give it FREE. Just pay for the shipping which would not cheap. Be best if someone in the Windsor/Detroit area who could come & pick it up. I really do not want to junk it. I think it may fit the 70-72 a-body cars. PM or email gball1947@gmail.com
