Ok so I'm working on getting 3 body mount bolts out....I've been soaking them with PB Blaster off and on for over a week. 3 times just today, and a couple times yesterday. Just tried to get them out with a 3/8" breaker bar. 2 of them don't want to budge, and one of them broke loose without toooooo much effort but I think I'm just spinning the captive nut now.
So, what are my options now that I broke the captive nut loose. It's the one the sits right under the front part of the Driver's seat. The other two I'm working on are the next mount before and the next mount after this one.

Are you saving your tub? If not, just hack into the floor around the spinning bolt. The two that are frozen, I would PB several times a day for a week. If you drill a hole in a strategic area through the body you can spray the end of the bolt. Some bolts are just too far gone though. Sometimes you can overtighten them and thus snap the head off. You CAN grind them off, but it's a royal pain, I just did mine. Or use a cutting torch, but watch for the fuel lines theyre right under the driver's seat. If you don't have access to that (like me) you can take your time with the grinder, or hack away at the floor around the bolt. Here's what I did to one of mine because I didn't care about my tub, and the bolt wouldn't move
Have you read this? This is the only way to get any penitration lube onto the bolt.
You have no choice for the spinning one. You are going to have to cut into the tub above the body mount and tack weld a new nut for the mount.
If it is the first one from the front, you are in luck. You can access it by moving the rubber peice that covers that area. Read the post it will show you.
