Does anyone know why my 63 t bird has a heater core with two pipes, when it seems the only one they sell for my car has only one?

Has to have a in & out for flow, never herd of one with just one tube.

That's what I thought, but if you go to MACs or some of the online core distributers, that's what comes up on the search.

Ford Thunderbird Heater Core, 1 Pipe With 3 Studs, Late 1962-63 Ford Thunderbird Heater Core, 1 Pipe With 3 Studs, Late 1962-63 Part # 66-34825-1 This is the one they sell.

Will have to look into that 1 tube heater core, like we said never heard of it. May have to do what Js08016 suggested...

Thanks to both of you, I went to NAPA, and they said bring it in, and they'll try to match it. If that fails I guess I'll look into getting it re-cored. Thanks again.

And of course mine would be the one without A/C. Maybe that's why they couldn't find it earlier. We'll get it figured out.

I'm going to pull it out this PM . I think you're probably right on that. thanks for taking the time to help me. Paul.
