I have a cab and chassis with the narrow 14bolt 4.56 1) Can I use srw hub to widen the rear not sure about brakes ? 2) What about spacers? I had some on a f350 once that made it able to run duals but I don't know were to find them. 3) Should I just swap gears to another 14bolt I have a few with 4.10's If I do this I can use 3/4 t spring hangers to make up for the with in the spring perches correct. I just didnt want to swap gears not scared just lazy.
