'63 Valiant V200 wagon - rare bolt issue

Thanks, Jeff - I appreciate your efforts. I did correct myself to 7/32-20, perhaps you missed it.
no problem I was looking at post #14 for the bolt...which says what is says. Use a bolt if you can with some anti seize. Self-taping screws are one time in and not serviceable. They also loose their tightness in a moving vehicle going over bumps.
