Adjustable Strut Rods

Is there value in adding shims to tighten the gap between the spring clip and the torsion bar?

Also, do you know of any poly strut rod bushing that are the correct thickness and locate the wheel side of the LCA in the correct location? Seems like if one would want to run poly strut rod bushings, they'd either have to modify the bushing, or use adjustable strut rods.
Well possibly, but it's also possible that the gap between the clip and the bar is intentional to allow for expansion. As some of the posted pictures show, Chrysler left quite a space there, so it must not be an issue if everything else is installed correctly.
