Ok, I've been planning and doing the math for the sas on my 1997 c2500. My plan is to use a late model (2005) ford super dana 60 (heavy a$$ axle, auto locking hubs, dual piston brakes). Utilizing the factory coil spring pockets on my truck for the coils, and utilizing the ford factory radius arm mounts on the axle for a clean stock looking swap. The issue i have right now is the factory spring pockets on the truck are approximately 36-37". Must of what i read about leaf spring swaps tend to have a 39-40" spread (outside frame rail mounts). Would there be a stability issue with the mounts this close on the axle?? could it possibly be solved by putting in a stiff sway bar? and mounting the shocks wide on the axle? This is going to be my first SAS so i want to have my bases covered. Any other issues y'all think i might run into with this type of setup?
