purchased an 87 runner with a SAS, since i'm pretty new to Toyota's, I was getting to know my truck, pulling stuff apart, inspecting etc. The space measures 3/4 of an inch. It was my understanding that I needed 1.5 inch on each side to be even with the later/IFS rear end. The axles look dead on width wise. PO states this was an All-pro SAS kit like 5 years ago....do you any off recognize this set up?
