Neil, I like your idea!! On my triumph tr6 ,for the trans tunnel, I welded in 1/4 weldable nuts, nutserts sounds easier;) Do you buy those as a kit, like rivets?
yes, they're available all over with lots on ebay like this 86PCS Nutsert Kit Rivnut Insert Hand Tool Riveter Rivet Nut Threaded M3-M8 Car | eBay
also known as rivnuts too when you do your own search.
