Im in the process of SAS on a 85 s10 blazer. The easiest was I can see to mount front springs is with a shackle at front and rear fixed mount. I know jeeps, sammi's and some furds did this, and alot people change it. WHy?? I did some research and the forward shackel seems best, other than teh giving up approach angle part. Other than that it seems ideal. Any input??
