Question: Not enough Caster adjustment in my big block Duster.

I am installing my Dana 60, mono leafs and caltracs. My brother came over with a set of adjustable strut rods he had no use for since going to a b body. I am going to throw them in and I might play around with the adjustments and see what it does to my caster. I don't have a caster issue, but since I have access to an alignment machine I believe I will play around and give feedback.
