I can think of 3 options. I don't know that you can't helicoil the plate. I haven't tried to do one that thin, but if you can thread it, you should be able to helicoil it. The challenge isn't threading or inserting the helicoil, but to break off the tang once the helicoil is in. If the helicoil is deep enough and the bolt is shallow enough, you could just leave the tang on the helicoil and be done with it. Another option is a Te-Co thread insert. Insert it with some resin to help it seal and take a set (it is supposed to already be resin coated) There is no tang to break off, so just put it in deep and let it take a set. It should hold nicely with the larger threads and the 3/16" bolts will have steel threads to run into. You could also replace the mounting plate. I know that is not a pleasant thought, but is an option.
