THANK YOU ALL SO MUCH! You guys saved my backside on this project. 10-32 is the right size for my 30/31 firewalls. Factory D nut, and there is just no way to get a #12 in that hole. I'm glad I didn't assume the earlier models were the same before making the harnesses. It's odd that Mike's catalog says the 12-24 fits 30/31 firewall when it clearly won't work on either of mine.

Thanks,
Kyle
