    I have read several posts that the only heater cores available are aluminium. I found these at summit. Made in Mexico, 1 year warranty, and the Summit Brand. 1967 and 1970, and they carry a full line of others. $50 and $80 + free shipping. Someday I will install them and we'll see how they fit, but they look right.

  2. Ames performance has the correct OEM style brass and copper heater cores. I just bought one last year for my 71

    I was one of the guys that posted about only finding aluminum heater cores. I’m thrilled to see that there is another option. At this point I’m not sure if I’ll go with a repo copper/brass over having my original redone by a professional, However, I’m glad to know I have a choice. Thanks 12lives & GranSportSedan!!! Mark

    Here's an update. Boy it takes me a long time to get things done.... IMG_0466[1].JPG IMG_0467[1].JPG IMG_0468[1].JPG IMG_0469[1].JPG IMG_0470[1].JPG IMG_0471[1].JPG
    You can see that it fits OK and covers the hole. It is a row smaller on the long side:
    I will post more after I get it back in the car. (Yes, I put the rubber seal on the inside and the out side - alittle more support as they do not have the metal piece that ties the two tubes together.

    The upper tube is rubbing on the heater box. Wont take long for that to wear through. The heater box is more rugged that that tube. New copper is not as thick as old copper. Bending it unless done properly, is a gamble, at best. I would be wary.

    I saw that too. I may try to slide the whole core over to center it. The small tube bends easily, the bigger one does not. edit - fixed.

    What's the issue with the aluminum units? I've installed 3 or 4 know with no issues. I don't remember any fitment issues.

    I got one about 3 years ago at the time only Year One was the only brass one I could find, just last week I went to pull the engine and attempted to pull the lower heater core hose off. Needless to say I am now in the market for a replacement as the solder job didn't hold very well, I may try Ames as they have good products usually, or maybe get a original one recored. This was for a 65.

    The Ames one "looks" the same as the summit. Yeah, I'd cut the hose off - the tubes are pretty weak, especially the small one.

    The newer brass/copper non-A/C ones are a row, or two short also!

    Man - I wish I had a "local" radiator shop. We lost the last three in the area about 4 years ago. I guess its cheaper to replace that rebuild the new units and the EPA didn't help either.
