I'm in the middle of putting Rough Country leveling coils on my '93. I got sidetracked by some rust issues with the spring perch stud and other hardware and noticed i had some leaking axle seals and a bad u-joint, so i had to deal with those first.
I took a 6x6x10 piece of wood and supported it with 3 jackstands to get it up and oddly enough, my coils just flopped out of the shock towers. I began removing the nut that holds the spring to the spring perch with my 1 1/8 impact, and when i got it off, i noticed my stud was almost rusted through. The nut part of the stud was also rusted almost off. It took alot of heat and pb blaster, but i was able to get the stud out and i ordered new ones because i'm sure the passenger side is just as bad. i live in the rust belt though. i hope you have better luck.
