there's no bolts holding the rears on. They're adhered to a C-shaped bracket that is held in place by the u-bolts. I used a sawzall on mine to trim them,and I tore the driver's side bumpstop off,so I siliconed it back on and held it in place with some zip ties ill it cured.
It also makes it alot easier if you have access to a hoist.
I wouldn't really recommend using a grinder. It'll take a little while and the smoke and fumes from the rubber is crazy. I just tried my angle grinder on my front bumpstops this morning and that was no fun,so I'm going to tear the front end apart and sawzall 'em off.
