Hey all, I tried searching all across the site but couldnt find anything regarding bolt identification. Im new to jeeps and have a 1999 xj. Im replacing the bumper but the bolts that are currently attached to it are completely rusted over so I cant accurately figure out what size they are. I have the service repair manual but it only suggests you salvage as many bolts as you can rather than identify the size.

Is there anywhere I can get that kind of information? Or does anyone know off hand what the rear bumper bolt sizes are?

Thanks in advance, I am sure I will have lots of bolts to replace as I restore this old beast.
