here is a pic of the last alignment done in august of last year.
i remember now it was mentioned the way the upper arms were mounted, [inboard of the chassis mounting point] all the shims were removed, and the camber could not be made any more positive.
this is not a constant "sawing back and forth" [unsafe] correction needed, rather just a minute thing that gets bothersome/tiring after a 3 hour drive.
of all the power steering conversions he and i have made over a 50 year friendship, this is the first one that has had this symptom/problem.
the vendor that supplied the box said this box is designed to be tight on center instead of having the minute play other boxes have.
tossing $100 bills to the alignment place every time isn't much fun, especially since i have the tools and know how to use them, although it is getting difficult to crawl around like i used to.
