I don't know the number on the q jet but it's from 1971 so it has accessible fuel/ air mixture screws. I also have one with the hidden mixture screws too but my uncle recommended using the 71 because it's period matching to my car. He currently has the older carb and is rebuilding it.

When you can have him give you the number off the main body of the carburetor he would have needed this number to order a kit.

I am willing to bet your uncle has already checked into this, and has it covered.

here is a link that will help you identify exactly what carburetor you have.

It sure would be nice if you stumbled across one of the rare High performance Qjets that fetch 2,000 dollars.

I'm confident my uncle will take care of that carb. He used to troubleshoot for gm and he is big into buying and selling old cars. It just sucks that he lives 45 minutes away. I did text him and ask for the number on that carb though I will post it soon
