Choke pull off mounting 69 l71

Hi, I was pulling off the choke pull off on a 3 x 2 L 7169 Corvette. The carburetors and motor was recently rebuilt. I could not unscrew the choke pull off mounting screws without great effort. I finally got them off and the very ends are stripped. Does anyone know the right size screws to mount the choke pull off to the center carbs. I may have to put in helicoil’s but I first want to make sure I’m using the right size screw. Thank you very much in advance for any help you can give me.

Most are 10-32. I've seen some list numbers with 8-32. You have the screw - just measure it, or measure the threaded hole diameter to verify.

10-32 screw diameter is roughy .190"

8-32 is roughy .160"
