    Yes 71 Skylark w/ AC, 455 swap. I saw the concerns with the corrosion on aluminum, one thing to keep in mind. Might see if i can have the OEM unit i the car currently tested and cleaned. If it checks out then i would run that. I was just thinking of the age of it might be an issue.

    I agree - re-core the original one if you can. The OEM units had a reinforcement strap on the tubes which the new ones do not.

    Scott,

    If you have a good radiator shop near you, have them recore your original with a Maine Auto Radiator core. They're out of Lewiston, Maine and have a website if you Google the name of the company.

    I just had one done a couple weeks ago for a very reasonable price. It was a little more than a repro but I'd rather pay extra for better quality & fitment.

    Something to think about.

    Nothing like an original for fit. The nozzle ends on them are better too. Aftermarket are leak prone and don’t always line up well with openings in firewall. It can be a fight to get them in.

    Not always true. Look at Brett’s. His is non AC though. I forget what an AC original looks like.

    I'll get the box removed to reseal it and have the core tested while everything is out. Being in San Diego CA I doubt the heater will get much use, if ever. I just really don't want to get a leak then have to tear everything back apart. The front clip is off and engine is out of the car so it is the perfect time to reseal and check things out.

    Considering it's apart, that's a good idea.

    Have it tested and recored if need be. Sometimes they test okay and once the hot water starts running through them, they leak.

    Man I would not be a happy camper if I had it tested only to have it fail later on lol. We put a man on the moon, I expect to be able to test a 40 year old heater core for leaks successfully :D:D

    When I had my car apart, I figured that I would replace the 40+ year old heater core. I tried two different brands from the local parts store, They both looked like they were very poor quality so I reinstalled my original. Hopefully in a few years I won't regret it. I got my car from the original owner, my Grandfather, so I knew the history of it and know that the cooling system was flushed every two years. It looked new inside.
