I'm getting ready to do a SAS on my 85. I currently have a super lift 6" suspension and running 38.5 boggers. Im going To be switching to 42x14x16 iroks. The monkey wrench in the project is that I'm gonna use the passenger side drop Dana 60 from my totaled 85 GMC and also the 14 bolt rear. I know, GM parts,but dont be a hater,I'm a ford man just using what I have.( my GM axles already have lockers,35 splines,disc brakes,hydraulic assist steering,and 5.13 gears) I'd be dumb not to use them. What I've found out so far is that I can use a Dana 300 transfer case and buy the adapter from advanced adapters that would mate it to my C6. This would give me a passenger side drop system. I really want to use coils and radius arms but my GM axles (of course) are already set up for leafs. I need info on whether or not I can go with coils or do I have to stay with leafs, and if so how much more lift do I need other than the 6" lift coils I already have? I also have the 12" leaf suspension from my 85 Gmc...is this usable on the bronco?
