72-80 RC/ truck Heater core
« on: January 21, 2019, 05:25:28 pm »
Hello All,

Just bought my new project, 79 RC se; my first task is changing the heater core as its leaking terribly.   I have found that the heater core for the 70-80's RC's and Rams with air conditioning has been discontinued and cant be sourced anywhere.   Has anyone found a suitable replacement.     I can get the heater core for the non air conditioned unit; but 'd hate to start cutting things up.

Any help would be appreciated




Edit, changed title to prevent confusion-SB

    I just went through this a month or so ago - took out the old one and took it to a radiator repair shop.  Cost more then a replacement one but then if it's not in stock is it really cheaper?  YMMV

    Where can you get a non-A/C model? I canít find it anywhere.

    Had the same experience as the other poster, radiator shop said they will re-core for $330....ouch!

    Yeah, plenty of 81-93. We are in need of 72-80. I think the core size is the same but outlets are different.

    Is there a radiator repair shop around you?  Might be worth a call...

    LMC seems to be the only source.

    I tried the radiator shop. IT was one of the only ones who said they could re-core since it was a discontinued item. $330. I was expecting $40-60, ouch! LMC replacement is $185. Its either that, or keep running it on bypass.
