Default Trying to identify inner heater core case by part number. Help!

I'm looking through the 53-82 parts catalog and cannot find the inner heater core case with part number 3014336. I have the final print of that catalog dated December 1983. I find others but not that part number. It's not a reproduction case. Anyone know what year, AC, or non AC this came from?


I've attached a couple of photos.

The case appears to have been spray painted black at one time.

The case on my '76 does NOT have this mechanism. Inside I see another blending door that this links to.

Here's the part number from inside taken with a borescope camera. You can see the original FP company marking and part number.

That's not a GM PN#.

You're not going to find that part number listed anywhere, because that's the number for the fiberglass case, which was never sold separately.

Like a lot of GM parts, the heater box was only sold as a complete assembly. The complete heater box assembly was made up of many parts, and each of those parts had it's own part number. These numbers were never published in the parts book, because they couldn't be ordered individually, but they were known internally to GM and/or GM's suppliers, so that the parts needed to assemble the finished part, could be identified.

It looks like 3014336 to me, but I agree that it is an internal part number (no pun intended), and only meaningful to whoever put together the heater box assembly.

I amended the "6" to the end of the part number. It's hard to see in the photo. Ah I see that makes sense. Does anyone know what year or what cable that blending door in my 2nd photo goes to?
