Projects Wcfb carburetor

I have a 300c 392 hemi with original dual wcfb carburetors , took apart for cleaning and rebuild but the rear carburetor squirter screw brought the threads out with it when removed, any body know what size drill, thread insert needed to repair it, to fit the original screw ? The carbs are 2534s and 2535s pt no’s

 

Measure what thread it has, then you know what thread insert kit (often with drill included) you need.

 

If you can’t make a repair, center sections are the easiest to find. There are quite a few different tops because of choke and fuel inlets and same for bases. Centers an all pretty close the venturi size can be seen looking in the body.
Repairing can be done in many ways today. Helicoil if there it enough room. Or thread repair epoxies with the screw using release agent on it.
