This is an '83-96 tailgate strike bolt installed in the hole for a '78-82 type using a large angle-iron nut plate (not visible inside). Although not ideal, it has worked fine for ~12 years of rough use. I suspect the reason it's holding up is that I keep the t/g aligned, so there's very little stress on the strikes.

It's barely visible here:
