I bought my A/C truck heater core from NPD. It looks good but haven't installed it yet. They appear to have the non-A/C truck version as well. https://www.npdlink.com/product/core...-outlet/194464

Just be aware there are 2 sizes of heater cores. See thread.

This may be called out on your SPID as Deluxe heater as mine is. 2nd column 2nd item.

I've also heard they were standard when shipped to dealerships in areas with cold winters so it may not be listed.

No deluxe heater on SPID

This truck was delivered to an Arizona dealer sold to an Arizona customer and spent it's whole life within 22 miles of its dealer in SE Arizona.

So it's likely I have the small core...maybe?

I'd roll the dice on that.

I had a '68 Skylark that the "replacement" heater core was about an inch shorter than the original. The aluminum "replacement" was the same size. One never knows what they'll get anymore, what with the Chinese stirring the facts.

I installed this non-A/C copper heater core from NPD in my truck about 2 years ago. It fit great, and I've had zero issues with it.

Classic parts one of my go to places even though an NPD location is close to me. They offer aluminum and copper/brass heat only and with A/C The copper heat only https://www.classicparts.com/1967-75...tinfo/68-231C/ There are dimensions provided to compare to original.

Are those little insulators on the tubes factory? If not, where did you get them?

I don't think the factory put insulators on like that, but I'm not 100% sure. They came with a complete heater seal gasket set I got from GMCPauls.com. The kit also included a large thin foam seal that goes between the heater box and firewall instead of using caulking or RTV. The kit is the second to last item on this page:

Thanks for posting that info. I have the foam gasket for the box to firewall but had not seen the ones for the tubes before. Back to your regularly scheduled programming...
