I'm trying to understand the proper relationship between the adjustable linkage (between box and lever) and the tie rods. assuming the front tires are aligned and the steering box is on center, i can compensate for too much left/right adjustment at the tie rods by adjusting the linkage between the box and the lever. Wheel and steering box will be on center, but this will cause issues & different behaviors when turning left vs right (correct?)

How do i assure that the tie rod lengths and lever positioning are as close to ideal as possible, and then adjust the linkage? Should i measure the length of a non adjustable linkage and force that length on the adjustable linkage? Then spin both tie rods to center the tires for alignment?

Sir: you can put the steering wheel straight with the box on center and adjust the drag link till the relay lever and idler arm are 90* from crossmember with a protractor then adjust the tie rods to proper toe.

Sometimes you will need that adjustable Drag link as not all came with
them. Call us or go to our site and we can supply www.gmcrvparts.com and
go to front suspension.

Thank you C Boyd. Clarifying the 90* is exactly what i was looking for. I wasnt sure if it was an exact measurement or more of a rule of thumb. I can work out the rest.
