So, I have been pondering what I should do to the Fly when it undergoes an overhaul. When I originally welded in a 35-40 Ford front crossmember, It was set up with about 4 degrees of caster. I am using a 36 front axle with an early 30's front spring. I moved the spring on the top of the axle and used longer perch pins. I am thinking I need to add more caster, somewhere in the neighborhood of 6-8 degrees. The question that is plaguing me is this: Do I need to remove the front crossmember and add more caster to it, allowing the spring to be in a more relaxed state? Or do I build a machined wedge to compensate for the angle of the spring? Make sense? Think of the angle of the spring relative to the crossmember.
