energy suspension doesnt offer a kit for the 86-93's (see link)
but they do offer one (which is mislabeled, says 93-97) for the 94-97 trucks....this kit will partially work, there are three size bushings in it, you can only use two of the sizes, one fits the leaf spring eyes, and one fits the shackle eye. problem is that you will end up short on the ones for the leaf spring eyes, so (what I did) call energy suspension and give them the bushing # stamped in the end of the bushing (i think it is 6051 but dont' hold me to it), and they will send you 4 more halves that will give you a complete set for the leaf spring eyes. now, before you install the ones in the leaf spring eyes, one of the halves will need to be trimmed @ a 1/4 off of the end that goes into the eye for each leafspring eye, because if you put the two halves together they will be wider than the leaf spring itself. also before you install the ones in the front eyes, the outer part of both halves will need to have between 1/16" & 1/8" removed/shaved so that it will install in the mount on the frame (if you look inside the front mount, the two screws that hold the pin/bolt into the mount screw into two fixed nuts, and these nuts cause interference with the total width of the bushings. this little bit of clearancing will save you much grief & agrivation.
I think I ordered my bushing kit from summit for like $35, and they mailed the extra 4 bushing halves for free....
