Sometimes, if you live right, you may be able to unscrew the frame-to-body bolts after generous application of solvent to the threads from above. More likely, you will twist the cage and pull out the spot welds holding the cage to the frame.

Nice pics, I wish I did the hole saw method rather than just cutting out with a grinder. Still works out in the end but probably would have saved some time.

Re: Rusted broken body mount bolts and cage nuts 67 ss convertible

i guess i lucked out on my 66 as i only had 1 bolt that broke,the one next to the drivers seat.i cut out 3 sides of a square with a cutoff wheel and bent it up on the 4th to get to it.i got a vise grip and heated the tip of the bolt and eventually got it to move took about an hour of heat and cool cycles but the bolt screwed out the top.

I've also rounded the corners of the square nut off in the cage, distorting the cage and allowing the nut to spin freely inside of it. Grrrrr.

Re: Rusted broken body mount bolts and cage nuts 67 ss convertible

You're right. No pictures or video of this that I could find. I'm getting ready to replace my body mounts and hardware. I like the hole saw method. And of course, all my cage nuts are broke loose.
I would like to see pics of the finished product before you welded the metal back in place.

Re: Rusted broken body mount bolts and cage nuts 67 ss convertible

Mine is a story of luck, just plain living right, or possibly having my jaw in the right place because all of my body bolts unscrewed and only had to replace 3 that were rusted badly. There are some success stories in doing this job in under 2 hours.

Your just jealous because you can't hear the voices!

When you put the new bolts back in make sure to use some anti-seize on the the threads so the next time YOU or the NEXT owner has to remove them they come out again, easily this time.
