Heater core isn’t fitting in Plymouth Duster

supertruck said
I bought one from Classic Industries for my 73 Dart Sport. Had the same issues. Sent it back, bought one from Rock Auto, and it fit perfectly. On the AC side I had to carry it to a radiator shop, with the old one, and have then bend and re-solder the new one to the same specs as the old one.

Do you happen to have part number for the heater core you got from rock auto? I just bought one from them but it was completely wrong. I thought I pulled the right one w/ AC but it didn't even come close to fitting.
