    I broke the upper shock mount on the rear driver side of my 86. Upon finding a replacement I took a air chisel to the top of the rivets to remove the bracket. Much to my dismay when I got the bracket off I still could not remove the rivets. I can not get at them from above to drive them out, nor from the bottom due to the gas tank and other cross members that are also riveted on. I know that a number of you have done this before, and I'm wondering how you went about it. I tried to tighten a bench clamp on them to drive them out, but that didn't even budge them. I drilled a hole in the frame for now, but I figure there is a reason gm engineers put the bracket where they did, and I would like to get it back on. Thanks for any idea or techniques that you might have.

    My Best rivet removing method is the torch but if you are set against it, drill them out. Use a metal marker to put an indention and the start with a small bit. Go bigger each time and take it slow to not wear out the bits

    honestly, the easiest way, is to take the gas tank out and get in there with an angled drill, either an angled airdrill, or an angle attachment for your regular drill, thats how i got mine out, if you do use fire, youd want to take the tank out anyway, exploding gas tanks hinder the repair process :)

    Nice technical article on rivet removal. I've typically ground off the head and hammered it through. However, if the rivet is tight it makes it a lot easier if you drill the shank half way through to relieve some of the radial pressure.

    I've removed my fair share of rivets, and I think it's easiest to do it with an angle-grinder (If there is enough space).

    First grind down the heads

    Then remove the mount, or whatever you want removed

    Then you have to grind down the remaining parts of the rivets as well.

    After that they almost fall out by themselves.

    I've drilled the rivet frist then taken the air chisel to it.
