My 86 has had new shocks several times and I just put some new ones on this past weekend. It had a BB with some rancho 5000 that had been on there for 4 years. PB Blaster overnight, couple hours before, couple minitues before, bolts came right out no hassle. I did the bastard pack S10 for the lift in the rear. I took the whole rear spring assembly apart and the only broken bolt was an old leaf center pin which was no big deal because it was garbage anyway. Maybe I got lucky or maybe it just goes to show what a little PB Blaster will do. Anyway I also put some RE 3" coils in the front, RE adjustable trackbar, DT3000 shocks, and some new BFG 31x10.5 AT's. No vibes just have to find time to do rear brake line, flex it out, and go on run sometime.
