Update. Got the carb apart further so Cliff himself from Cliff's High Performance, literally the guy who wrote the book on how to rebuild and modify Quadrajets, could Identify it to put together a parts kit. Just my luck, when he identified it, he said he's worked on quadrajets over 30 years, and he'd throw that in the trash and start with a better core. He said this particular carb is the one that gives all quadrajets such a bad name like "quadrajunk" and quadrabog, etc. So i'm watching Ebay for certain coded quadrajets now for a core worth rebuilding.
