Secure Side Cover For 2001 Thunderbird

Hi All, I have a question about securing the LH side panel (T2301266-PG). The panel top is secured by two plastic pins that's part of the air box (T2201221, upper auxiliary chamber). The rear pin has snapped off so the panel is not secure. Rather than buy a whole new top for $50.00 or use a zip tie, I'm thinking drill out the remaining old pin and cement in a similar plastic dowel. I haven't removed the air box top to see how the original pin is attached.

Any suggestions/comments....?

Thnx in advance! Rich
