This is my first Chevrolet. It runs good but the stock brakes beyond suck. I have a set of Wilwood fronts on the way. I'm doing a ton of maintenance...complete bushing kit, all u-joints, hubs, tune up, hoses, belt, idler and tensioner...you get the idea. I've ran into a snag. When I dropped the exhaust, every cat stud (part #10219507) https://www.ebay.com/sch/i.html?_nkw...LH_TitleDesc=1 on the drivers side broke off, I have no issue drilling and tapping to repair the hole in the flange. The issue I'm having is finding suitable replacements for the hardware. Has anyone ever had this issue? Thanks for any advice or info.

 

Welcome to the forum.
Have you tried a Chevrolet parts department? There's also a lot of aftermarket Corvette suppliers that you might check with to see what they have.
