Technical Heater core repair

The heater Core on my 63 Rambler American is in need of repair. Cant find a new one, and the AMC vendors arent much help for my year.
Does anyone have a shop they recommend I can send mine to and have it repaired?

 

Have you tried these:-

Some radiator shops can repair them, I've had several fixed locally by one.

 

Do you have a old school radiator shop where you live, the real repair shops can usually repair a core. HRP

 

I havent been able to find any close by.

Heater corer's usually don't spring a leak in the core like a radiator but the top and bottom tanks can separate and leak. Most shops will just order or cut a core, clean tanks and solder back together............................

 

Some heater cores are easily modified to fit a new application. A hole saw, some pennies to block off old holes, and some copper tube for odd bends, and a big-assed soldering iron.

 

If you can't find a local shop, these guys can do it and they ship. I've had them repair a radiator in a '40 ford big truck and also modify a '39 Ford p/u radiator. Quality work, fair prices IMO.

Thanks for the link.

 

Best bet is to go through a catalog and find something of similar size. I know a couple of the AMC guys have swapped in other cores -- that one is pretty easy to do due to heater location -- but I don't recall what they used. Easy to mod where the inlet/outlet is -- as long as you don't mind drilling the fiberglass cover.
