Broken Bumper Guard Bolt. Help Please

[THE "10" SILVERADO]

Got to go to the salvage yard again today, only my second time . Love that place.

Anyway, out of probably 50-60 trucks between many yards there was only one set of those push bumper guards. So I snagged them, but I ended up shearing off one of the bolts on the guard. The thing is welded onto a plate on the back of the guard so I am wondering what can I do to fix this?

LMC sells the repro's for like 150$ and I couldn't find any others so this is what I have to work with. Has this happened to anyone else?

Any idea's on what to do to be able to use these are appreciated.

Thanks!
Michael
