Installing Windshield Brackets on Race Car, What Size Rivnuts Should I Use Options

[motorvated]

Like it says, I would like to be sure that I buy the proper size Rivnuts to affix the rubber backed aluminum brackets I fabricated to hold my windshield in place on the race car in the event of an impact. The metal of the windshield surround and of the cowl seem to be quite thin, and the Rivnuts I'm seeing appear to possibly be too deep to hold the Rivnut tightly in place. Anybody used Rivnuts for such an application, and if so, what size/dimensions did you use that worked well. Thanks, Mike.

Chris beat me to it.
Or, alternately, if you have a need or desire to be able to remove them often and want to use rivnuts you could rivet small reinforcement plates using backing washers on the rivets, then Rivnut to them. I used this method at the attachment points on my fiberglass front and rear lids that use Camloc fasteners.
