Welcome to bronco Zone, and thanks as well for your service!!! While the Dana60 SAS on my 84 Bronco uses the leaf springs in front and rear, I did plenty of searching on 4 links and such. You can install a triangulated 4-link and coilsprings or coilover shocks in the rear, but I would suggest doinga 3-link on the front D60. A really good option I considered was using the Cage offroad arms, along with an adjustable tracbar. I decided that while I may do that at some point in the future, I wanted to first get the 1-ton axles under the Bronco and get her running on some trails. I also had some interference issues with the frame outriggers for my rollcage and modified tranny crossmember. These issues are something to address with any type of SAS (Straight Axle Swap), as things quickly become cluttered underneath the frame rails. The leafspring setup was far more simpler to install as well.
The parts list for DOM tubing, Heim joints and mounts was a bit over $2200, but that was five years ago. I would suspect these parts to run about $4000 now, excluding the donor axles. I'm not even sure is Cage is still in business? one of the best websites I've found for serious suspension mods is Pirate4x4.com for all types of offroad rigs. You can also check out the extensive SAS forum section over at Fullsizebronco.com, which has many members with SAS'd Bronco's. You may also look up Miesk5's Homepage of Bronco Links and visit the suspension sections.
