Yes the rusted bolts. I want to replace them but there is other stuff more important at the moment.Are you referring to the rusted bolts? If you can't get a socket on them, I'd pin-punch the center and drill them out. Soak 'em in PB Blaster and use ez-outs. Replace the lights with new - Stock TJ taillights are pretty cheap.
Vice grips and small bit of wet cloth wrapped around them??They are so fucked up. I tried, they’re like circles now
Nope. I have the right side on and it looks weird now, might just take it off till I can figure out what to do with this lolVice grips??
Do they go into rivnuts in the body? (I haven't worked on my tail lights yet)
If they do, you could grind the heads off to access the riv nut in the body, then drive out and replace the riv nut.
I'm going thru the same thing underneath with the mopar rock slider install right now.
PS: I've got shit that has had KROIL sprayed on it every time its on the hoist since April and it won't break loose.
Here is an extended reach cut off too that would be handy ($40):
