When I did my sas I stretched the wheel base 3" to help get a head of the bump. I also used some thin pieces of metal to shim behind the bucket and between the frame. I used the buckets from the 78 f150 donner truck. They sat approx 2" higher than the stock alowing me to run 5.5" lift coils with only 3.5" of lift over stock. With that said I ran into trouble with the steering box and track bar clearing each other. Just my 2 cents.
Yeah after doing some measuring and moving things around today 3 inches forward is exactly what I came up with also. What trouble did you have with the steering? What did you do to fix it?
