im about to start replacing my bolt in ball joints here at home.............will grind out the metal rivets and replace with bolts included with new joints. i realize i need to make sure the lower a frame is supported up to keep the spring in place, but are there any other things i am overlooking? blocks underneath for safety first. what bout a cutting torch (and a steady hand) to remove the rivets.....bad idea?
thought somebody might save me now before i kill myself lol.
looks like a pretty easy job.......will only replace the one upper that appears to be out.

thanks for any advice scorns or comments
