In this instance I can chop upto 1" total without modifying the
frame. From what I had read else where, the 1/2 ton 70's
front suspension was for the early 1/2 ton trucks. I ran
across one person doing a conversion to a 3/4 ton and was
using a 3/4 ton late model front suspension. He mentioned
that it was only 2" per side difference. Thats why I was so
surprised by my 3.5" difference.
