'75 Duster steering issue

Guess I should have read the post a little closer.
I know its more $$ but buy a fast ratio borgeson box and be done with it.
Not sure I want to spend $650 for a steering box. The Boregeson is 14:1 where my factory power box is 16:1. I am thinking either add more caster, or check the length of the idler arm and the pitman arm. They should be the same length center to center, correct?
