i am resurrecting my abused old 93. replacing a couple of broken mounts. i broke off 1 mount bolt in the hull. has anybody fixed this? is there a metal nut of sorts bonded into the hull? or are the bolts threaded into the glass? i know drilling stainless bolts is next to impossible. my possible options are; leaving the mount with only 1 bolt. putting a splint over the broken side with a couple of lag bolts straight into the glass. drilling thru the mount plate, which is also stainless, and lag bolting it there. anybody with any thoughts? thanks.
