New old stock GM part 3975439 radiator core support for 1970 Monte Carlo w/AT, CAC, HDR, 454. The number changed or crossed to 3963357 which is for 70 Monte Carlo w/CAC, HDR, AT exc 454 also for 400-4BC and 454 exc HDR, CAC, AT. We know that all is confusing, but GM would do that - sometimes, a dealership mechanic would have to make minor changes to the part to get it to fit - not sure if that is the case with this one.HDR is heavy duty radiator, CAC is air cond. How we read those part numbers: this core support is for all 1970 M. Carlo with 400-4BC, all 454 models and all Monte's with HDR, CAC and AT - but PLEASE look those part numbers up and make your own decisions for you car's needs. Very hard to find new old stock. Just a few notes from us.. We try to make anyone looking at our auctions aware of any defects we see. Look photos over closely, there are scrapes, scratches and shelf wear - maybe a slightly bent corner at times. These were not handled well in dealerships. Now a few notes from the core support.
I have no idea what bubble wrap or tissue paper is. I have spent my life getting moved around without so much as a box to protect me. I may have a few bent edges again from all the shuffling around I have endured.
I have been patiently waiting to be put to use so I may see the world. As of now, we are planning on attending the Commerce Swap Meet on November 7th in northern GA & the Moultrie Swap Meet November 20, 21 & 22 in southern GA. Look closely at the photos if interested in picking it up at these swap meets.
