    So I have a small leak it looks like on my heater core. Anyone know where or who has a good replacement? I would like to have mine record but that’s not going to happen as of right now due to time restrictions. I don’t want to have to replace this again later on down the road.

    Summit and GroundUp have the nice heavy copper ones that will fit the housing

    The best bet is to have it re-cored if you have a good radiator shop near you and it's not your daily driver.

    If you choose to go that route and can't find a viable shop near you, I'd be happy to have my guy do it. You'd just have to ship it out here to MA.

    Or you can roll the dice with the repros.....totally up to you.

    Brett's guy is top notch.

    I went through the replacement of the AC style heater cores for my '71. Year one and Ground up did not work. Year one was advertised as brass/copper, came in aluminum. Ground up came in with defects that prohibited its use, this could just be a one off but still was wasted time for me. So I went the re-core route (twice technically lol).

    If your tanks are good, re-core is the better route, just the more pricey route.

    Good luck!

    I used the summit on my 70 AC car with success last year. See my post. Doing a 67 AC car now...
    'Course you could just bypass it for now if you don't need heat and send it to Brett.

    This is the re-cored one I had done last year.

    i know of a local radiator shop that can do it. I just need to drive an hour to talk with them. My only thing was I didn’t want to have the car torn apart that long and down that long. Not home that often due to work. Brett you know about what it cost to get one record?

    Mine was $185 and the turnaround was about a week.

    Obviously shipping would add to your cost but the quality and fitment of OEM stuff is hard to beat.

    Aftermarket outlets suck. They are not nice like originals. They often leak with correct style wire pinch clamps.

    Brett, what size is the core and do you know where your guy got the core from? and possibly a part number for the core. I am talking to my local radiator shop about it. He found it but I just want to double check.

    My radiator guy is away but whichever one is for the 70 - 72 non-air A-body car will work.

    Maine Auto Radiator will know which high efficiency one you'll need.

    Well, I just got quoted $155 for a re-core of my heater core. I will probably pull mine out and take it up there when I get back home, unless I have a spare, which I might.

    That's a good price.

    Did that shop get ahold of the place in Maine?

    He said he gets the cores out of Indiana. He looked everything up to make sure it was correct. Said he does a 5 year warranty on all his stuff

    As long as it's made in the US, you should be good.

    Looks like I need a heater core, just noticed coolant on the floor when I rolled the car out of the garage to measure my suspension. Inspecting it I can see where the impossible nut behind the inner fender is missing meaning that it’s probably a replacement heater core already in there. Since I don’t know what’s in there I’m not sure it can be recored, especially if it’s an aftermarket aluminum one. Summit doesn’t offer a brass core for a non AC car but TPP does, any luck with this one or another suggestion?

    If your plan is to replace it, pull it out and go from there.

    I'm surprised that nut is missing, considering most of these cars only had that type of surgery once. Of course, that's not gospel but you'd definitely know more once it's out.

    If it's already been replaced, you can weigh your options once you know what's going on. I'd still look for a Harrison core to get redone as the aftermarket stuff is suspect.

    Which what be might you're seeing now.

    Or could be collision damage / fender repair.
