Default Body mount #4

I am trying to get mount #4 (behind the rear wheel) out and the bolt just turns. I can hear the nut on the inside turning, is there a way to get to the nut or do I grind the head of the bolt off. And then what, how do you repair it.
Thanks

You'll probably end up grinding the bolt off but before you do try sticking a large screwdriver or something similar down into the access hole to see if it will wedge the nut in place. If you are planning on removing the body I would just go ahead and grind off the bolt head.

To replace the nut and cage you have to grind off the aluminum rivets that hold the reinforcement on, remove it and then drill out the rivets for the nut cage. Replacement parts are available through Zip and other vendors. I replaced the reinforcements on the 72 but I'm just using bolts to hold them on. The weight of the body and the body bolts clamp them to the frame anyway. No NCRS scrutiny for this car.

Thanks for both options. PB blaster doesn't always work.

My mount and everything was shot I ground off the head of the bolt and drilled out the rivets and got rid of it all. Then I shimmed the body up and ground off the #4 mount and rewelded on a new one and replaced the rubber grommet, shims and let the body back down shimmed it up correctly and used a nut and bolt to hald it all togther.

I ended up grinding mine off as well. Then after I removed the body I rewelded the captured nuts assembly on both sides.

How do you get the old nut assembly out and secure the new one. Is it riveted on? How do you get to the rivets?

With the body off you can easily access the mount. I used a sharpie marker to mark where the center of the should be. I then used a hand grinder to remove the old mount, it has been a while I cannot remember how it was secured, I know I welded the new one, the nut sets free inside of the cage to allow for movement. I have used paragon for many years, as a matter of fact I use all the venders, however paragon is the first catalog I pick up, their parts seem to be very correct. Good luck!
