Hey thought I would pass this along. I've been working on my heater box and heater core in my 62 belair and was looking for a new one. I found they were pretty expensive. NAPA wanted 138 bucks for one plus shiping cause it wasn't in any of their wear houses. But my guy (awesome by the way) said bring the old one in, we have a book with dimensions, maybe we can find something close. Well he found that a heater core for a 67-68 Camaro with a 396 (has to be 396. Must have a different heater box?) would be close, BUT he had to special order that too. So I checked at Advance auto. The said, Oh yea we can get that overnight. And if it was wrong, just send it back no big deal. Oh AND it was $41.99!!!! So ordered it up, I cannot tell the difference between the Camaro one and my old one except the new one is shiny!!!!! Thought this might help some one out!!!!!
