Default Heater core issues

This is for my 77 with a/c. I just received my replacement core from a reputable vendor and after taking it out of the box it is similar but different then my leaking one. It is noticeably thinner so the hold down straps no longer will hold it in place and the clamp that holds the tubes will no longer fit as the new tubes are much closer together. Have any of you guys come across this? and if so what did you do? This one I see is made by Spectra which is the brand I could have purchased at my local parts store for nearly half the price but opted to get one from a vette parts supplier to avoid any issues. Does any one supply a proper one?

By all means send it back, I'm sure you can find one that fits properly, or at least pay less. Mine is a '69 and I got my core from NAPA. It was a perfect match, but it was 12 years ago. Good luck!

I also used NAPA but I have seen someone on here use rubber blocks to make up the space you are missing ...

I replaced the heater core in my '80. The guy at the Corvette Shop ordered me a core for a non-A/C car which was different. Blew me a way because all he does is Corvettes and you'd assume that he knew that all 80's had A/C as standard equipment.

My replacement came off of Amazon. A friend runs the local 1800 radiator company and recommended it to me. It fit perfect and is american made, out of Tennessee as I recall. It was about $60. (Oh, and my 79 is an A/C car).

Hi, I have a 72 w/AC and when I changed out my heater core, I had a really hard time finding one that was exactly the same dimensions and thickness as the original core. I bought a couple and sent them all back. Then I contacted Paragon Corvette and there's was exactly the same as the original! I'd try Paragon. It was copper and fit perfectly with no mods, as it should! It cost me $79 shipped last year.
Good luck

PS- paragon part #5770 for GM Part# 3015145. Replacement Style fits Corvettes 68-77 with AC.

I also went with the napa unit, perfect match.

The Napa cores are the Mexican units.

Ok here is the resolution to the issue for me. I had considered buying from one of the suggested places from you guys but before doing that I received word from the vendor that they would like to handle the problem. They were quick to send a return label for it and also checked into there supplier to see what happened. They ordered some new stock and after making sure they were proper sent one on to me it arrived and is correct in size shape and it's also copper, wrong one was aluminum. Not sure if it's proper to name the vendor, I didn't in the beginning as I didn't want to speak poorly of anyone, so if that's a no no please let me know and I will edit this, but there general concern and promptness to which they resolved the problem has made me a definite repeat customer of Willcox corvette

Glad you got it resolved. It's such a miserable job with perfectly fitting parts that you sure don't want to add any complications.

Regarding your posting of the vendor name, seems to me that they stepped up and resolved the issue. Very few of these vendors make the parts they sell so mistakes will happen. If they're willing to take care of these issues, I can't see a reason not to post their name since it's a positive in my mind. It has also been my experience with them and part of the reason I keep going back.

That's too funny. I went through the same thing last month with Willcox. The spectra was the same unit the local parts store had and needless to say I experienced the same problem. Willcox sent a return label but unfortunately did not have a copper one so I had to grab one from Zip. I have nothing but great things to say about Willcox and Zip.
