Help With Body Mount #4 Please.
How would you repair this body mount to last the life of the car? Keep in mind the car is not transportable and I can't remove the whole mount and tig weld a new one in due to space restraints. I haven't removed the other side yet but it's going to be in the same condition. I have the new energy suspension bushings but I will now need new bolts. What size and grade of nut and bolt should I get for #4 mount.

Afternoon Steve, I was thinking of attempting to fab up a 1/8" (what gauge is that) metal plate to surround thet op and sides of the mount. I would pre drill the opening (at the top) and then cut and grind to contour the front edge. Then I would tig weld around the front lip. I think the tig torch would have no problems if I welded all along the front edge.
What about some flat bar and just bend it in a vise and trim the front edge.
Thanks for chiming in stpman and I'll add the bolts to my list. This car is getting to me and

Just so I understand, I can raise the rear of the car approximately 3-4" so I have clear access to tig weld in new #4-#5 body mounts without removing the other 6 mounts?

Valid question:
Reason being is the car has sat for 20 years and everything and I mean everything I've done on this car has taken me 10 times longer then I thought therefore I'm at a point that I just want to get motived again by getting this car back on the road. I was going to drive it next summer and replace the other 6 mounts this time next year. I only wanted to replace the two rear since they were the worst of the bunch.
Here is a bit of my history lately and it doesn't end there.

I really don't want to remove the gas tank since that's just going to open up another can of worms. I was hoping this wasn't going to be another problem.

Well in that case I would lay a plate in on the bottom side of the mount and MIG it in. Problem solved. Then when I replaced the rest of the bushings I would lift the body and replace the rear mounts.
Seriously though I think you are putting to much thought in your past projects. Most of them are not fun projects. I may not live in Canada, but I am in the rust best in NW Illinois so I understand the pain.

If all you are looking to do is replace/repair the mount on the frame then I would cut off the top portion of the old mount with a sawzall or air powered cut-off tool to get to good weldable metal and then make up a piece of 1/8" flat steel and then lay it on top and weld it in from the bottom of the mount.
Actually, you may need two pieces of flat stock to make up for the loss of height. You could also replace the entire #4 frame mount

I dont know what shape your #4 cage mount is in but mine were completely gone and someone had made up their own nuts for the body mount bolt to go into and as mine is a convertible that rear mount is a bear with internal #4 body mount cage that supports the decklid hinge.

Odd, I had posted earlier but it's gone now.
Anyway, I had the same issue on my 67 Chevelle. I bought some large, thick washers and welded them to the mount. Looks like you still have plenty of good metal there.

Tigging with the gas tank in the proximity shouldn't be a problem. Just block off the area as best as possible with a welding BLanket or something similar.
You are on the right lines of you openning up a can of worms if you try and pull the other body mounts... When I did mine the #4's were similar to yours and the #1's were the same. the 2 and 3 captured nuts spun so I had to cut the bolts. I was doing a body off so getting at the captured nuts wasn't a problem.

This is exactly they way I started with my resto.-left #4 was in about the same shape as yours.
7 yrs later -all new mounts, new frame pieces, donner bird cage rocker channels, Mostly new under the body brackets(lots of them), new windshield header, new tank, all new rubber bushings,bearings and the list goes on and on.

Why not cut it off and weld a new one to the frame?
