So in my mind when i do mine i need an accurate degree of where the pinion is at, an accurate guess of what angle I wish to point it at, and then from there once I reset the perches to reflect what I wanted the pinion angle to be set at I am ready to set my castor at the 4 degrees.
Just thinking out load here....

An excellent answer. I get calls all the time on our Cut/Turn housings and "how come you won't weld the spring perches on". There are 3 critical angles on the cut/turn process, caster, pinion angle and them spring pad angle. While we used to try and do all three for mail order customers, we found its just too impractical to get them all right 'most of the time', so instead we do the caster and pinion angle and recommend customers set them under the rig under load for the spring perch setup. The caster has an ~3* acceptable "range" thus we can nail the desired pinion angle without too much concern.
