All of my pics from this truck are on the home computer, can post them later.
I used Jeep YJ dana 30 and a dana 35 for the rear. At the time there were no SAS kits for these so I made my own which is why I wanted the front out of a YJ with the spring perches already in a good spot. Then I built around those measurements. I think there are kits out there now with front spring hangers in the proper width for these axles.
I used 4" front Toyota lift springs from All Pro Offroad and mounted them under the front axle. They were very flexy and rode pretty good for a light vehicle on leaf springs.
The steering consisted of a 2wd steering box which I sourced from an Astrovan. Then a Jeep 4" drop pitman arm which bolted directly to the box. And the stock YJ steering linkage, of which I had to trim .75" off each end of the drag link to make it 1.5" shorter total becuase the frame rails must be a bit closer on the S10 which put the steering box closer to center. No big deal.
The rear S10 springs remained stock but I had to cut the stock spring perches off the Jeep rear axle and weld new ones on in the S10 location. I should also mention the rear I flipped from spring under to spring over the axle which gave me the rear lift. I would not have chosen the d35 rear axle but could not pass up the deal I got for the matched set with 4:10s, lock rights front and rear, front one piece axle conversion, and the steering linkage all together for $200. A Ford 8.8 rear from an Explorer would have been a stronger choice but I used what I had available.
Front d-shaft was custom made, ordered from Tattons. Rear I had made locally.
Here you can kinda see the front spring hanger. I bought one but it was too short so I cut it and sleeved it for length.
Front parts, better shot of the front hanger.
Front done, before starting on the rear.
Rear done, no d-shafts.
