There are no replacements except at Jim Carter and he wants $225.00 just for the core and I still would have to pay to have my tanks and copper put on. another 100 bucks.I guess its obvious that unless I can find NOS (ha) or another used one that is any good I will have buy an aftermarket one such as the one Classic Chevy has.($160.00)I would like to keep "RT" factory.
Suggestions?

If you are into an at home repair, you can pressurize it with couple of pieces of heater hose and some valve stems clamped in the ends. Use a bicycle pump to add a couple of pounds and then immerse it in water. After finding the leak, pull the fins or webbing off around the leak. This leaves a nice salmon colored clean copper exposed. Do the repair and retest. I did this and it worked until it got warm and then it leaked again. | | | | | Joined: Jul 2006 Posts: 327 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2006 Posts: 327 | Kevin Is it the round type like in the 1954 3100????
If you keep an eye on ebay you can always find Heaters that are ratty but you may find the heater core is good and repairable or try to get he old one repaired...
