I also got a 4 inch drop bracket for my sas, but I'm running 9 inch coils. I found that the frame on the doner rig was strait, and on my 94 was angled up, so I ditched the brackets and fabbed one up on my own. I have seen a sas done on a 80's with it just bolted to the frame, and I didn't like the angle that the radius arm was going threw the bracket. Hopefully I'll have pics on here soon of my sas.
