Im currently removing the body from the frame and I seem to have come across a problem. I thought I had removed all body mounts, but I still cant remove the body from the frame. If anyone has a diagram or may know where I might be missing some mounts please let me know.:yes:

Did you get the ones under the firewall bulkhead? If the car is on jack stands there are acess holes for all mounts that you can follow going up the frame rails plus the radiator support mounts.

I was using this for another discussion about half a year ago. Disregard the red arrow.

mount #4.. the ones under the rear seat... (need to cut metal back to expose bolt)

I remember 10 donuts when i did the 68.

mount #4.. the ones under the rear seat... (need to cut metal back to expose bolt)

and why do you need to do that?
it bolts from the bottom not the top.

and why do you need to do that?...



Because when the bolt snaps off from being frozen in there, you have to weld a new nut inside the floor-pan !:yes:

I wonder if Joel ever figured out his problem? :confused:

I will be doing the same thing very shortly. Then how do you get the new nut in when the old rusty bolt and nut snap off?

Its a square nut inside a cage, its made so the nut can move around inside the cage, but the cage isn't a lot bigger then the nut, otherwise the nut would turn.

You go inside the car looking down at the floor, and you can cut a U shape in the metal and kind of peel it back, then spread the sides of the cage, like the top of the cage back a little, then pull out the nut with the broken bolt out.

You can reuse the nut, just put it in a vise and maybe some pb blaster and get the broken bolt out, or if you have a torch heat it up.

I usually run the same size tap through the nut, clean the threads up a little, you want the new body bolt to turn freely .

Then put the nut back in the cage, and bend the pieces of metal back to where they were originally, and put a little weld in there so the cage is strong.

When I update my floor pan thread, a day or two, I took some close up pictures of a support with the cage nut in it, they should be pretty clear, then we'll have a cage nut to show what they actually look like.

Rob

Thanks for your help guys. Im trying to follow in my dads footsteps with restoring cars so this is my first project.

I just trecieved my body bushing kit yesterday and I have bushing #5, which is just rubber, no bolts and sits under the front section of the 1 piece trunk floor pan. I am putting them in to use for alignment of the pans.

You could apply some copper anti-seize to the bolt threads before reassembly, to be sure those bolts are not rusted tight the next time you need to remove the bushings. After 30+ years they will be rusted again.

When I removed my old bushings, the bolt broke at Mount 2. I had to remove the fender and wheelwell to get access to the caged nut to fix it. Also I forgot to release the auto-trans shifter when I lifted the body, and almost broke the transmission case.

I went to remove mine tonight but both #6 mounts spin in the cage, the rest of the bolts are out. I can't see how to access them, any suggestions?

Jon, according to your profile your working on a 69. That cage nut is in the trunk support, I just went out and measured it inside the hole with my finger.

I would go after it from underneath the car, start by cutting a hole with an air cut off wheel or dremel cut off wheel. Go about 1 1/2 '' from the center of the hole back towards the back of the car, and 1 1/2 '' from the center of the hole towards the front of the car.

Make your cut about 2 1/2 '' wide, so you have a hole 3'' long by 2 1/2 '' wide, only cut about a 1/16'' of an inch deep, then bend the tabs back and pull out the nut and bolt.

Also you could leave one end uncut and peel it back like a can opener, the just pound it back when your all done and weld it up.

Anyway, thats how I would do it if I had a welder.

Rob

Thanks Rob, Sorry I am working on my 72 while my 69 is at the body shop. I don't have a welder (yet).

When you cut the holes are you going straight through into the trunk or are you staying underneath? There is not a lot of room to work around these bolts.

Just into the suppport thats welded to the trunk, so you aren't going up through the trunk.

Rob

Thanks, I will give it a go. I was hoping to get a 1 inch wrench in there some how to hold the square nut so I can get it out.

Just make the cuts, because your going to tear up the sheet metal with a wrench, and its easier to get the edges back straight with a nice neat cut, trust me.:)

Rob

I'm doing a floorpan update right now, the bride is resizing the pictures, about an hour I will have it on the body shop section, I took two clear pictures of a cage nut, just so people could see how to handle them.

Rob

I'd go through the trunk pan, but that's just me...

The support underneath is thicker metal, easier to weld back in with out distorting it, its hard to keep from warping the top thinner metal, and you can't get a dolly under it.:p

Rob

Todd, when you have a trunk pan with a seam this tight, now you tell me, would you want to cut into a pristine trunk floor like this, it would be worse then trying to doctor up the Mona Lisa.:)

Rob

ehh... I guess...

Thanks bare metal your looking at. I'm going to get you an appointment with wallmart optical, and get you coke bottled up.:)

Wait till you see it after I layer the bondo on it.:)

Wanna see my metal? :D

Cool.

Cool.
Sorry, it's not at the 1000 point show car status, yet. I'm betting most people would've left it were it sat if they saw that rust... :beers:

A lot of them would have, but theres a bunch of guys on here that would fix it. Those are my favorite rim.

Heres some cage nut pictures, took them last night.

I took a picture of the cage nut because people keep asking about them on different
forums, so I figured I'd put this on the site so I can refer them to what one looks like.
There is a square nut underneath that cage, but they usually have a broken bolt sticking
in them. Anyway when you go to fix them, the side of the cage that holds the square
nut will be torn. Because one side is out, the nut will spin. Usually to get at these
it's best to go through from the inside of the car through the floor. There is normally
a hump in the floor where the cage nut is located. If you cut an "L" shaped hole in the
floor about 1/8" deep you can peel it back like a can opener, take your cut off wheel
or Dremel cut off wheel and cut the cage open a little more and get the nut out.

Once you get the frozen bolt out of the nut it's best to run a tap through it, then
put it back in the cage, bend the sides up or weld a little piece of metal in there,
whatever, but make sure that the nut will move around in there without spinning
around and around.

Another view of the cage with the nut inside of it.

Rob

Here's what usually happens when you get the dreaded spun cage nut;

That is a prime example of what most of them look like.:thumbsup:

Went by my body shop to check on my 69 today. I asked him about my 72 cage bolt problem. He told me to cut through the trunk with a hole saw to access it but save the cut out. I may have to sawzaw the bolt and remove it. He said to replace the bolt and bushing and he will tack weld the bolt and weld the metal back in the hole, grind it and paint it.

Does anyone sell replacement cage nuts?

Hopefully when i do its frame off in 10 years all of the bolts will come out again easily.

All the resto houses should have them.

If you can't get to them under the trunk floor you'll have to cut a hole in the trunk floor to access the nuts. You can usually see the trunk floor dimpled up where the nuts are.

Thanks for all your help. I cut a 3" hole in the floor at the dimples. Took just a couple of minutes. I put vice grips on the nuts and was able to get them out. The body is now resting on 2x4 blocks on the frame. Clean up time!!
