Skid Plate Bolt thread stripped

My '07 E83 needs the front driveshaft replaced. Had a back issue & ask my son to help with this project. Unfortunately he stripped the left front bolt on the skid plate turning it the wrong direction. Anyone removed one of these bolts with this problem? Once the bolt is out, What does it thread into? We tried a pry bar to put pressure on the fastener in hopes it might grab hold of the good threads & get it to come out. No luck with that. I looked at RealOEM, but it doesn't show what the bolt threads into. My concern is after the bolt is removed, what am I working with to thread a new bolt back in?

happens sometimes

>the bolt threads into the subframe .....we have found several stripped over the years ......just go a little oversize/tap in a new thread close enough ..... or...... drill the hole out a bit and use a nut and bolt with washers....also .....the plate is described as "structural".......so ....get it nice and tight

Thanks all. I just wasn't sure what I would be working with once the bolt is out. Looks like I'll try an oversized bolt & tap. Thanks again.

Thanks SwampX3. That video does help. You mention the ground cable. That was one of the earliest things I did on my X3 to cure the slow crank. I made a strap from 2 gauge battery cable, & cured the slow starter for good.
