The issue most folks have had is that the poly bushings end up being too thick, which pushes the LCA backward and therefore reduces the amount of positive caster you can get, which is already an issue unless you're running tubular UCA's with additional caster built in. This should be less of an issue with the 73+ struts, but that doesn't mean it can't happen.
The other thing to check is for any binding, if the bushing thickness isn't correct the effective length of the strut rod will also be incorrect, and that can cause binding on the LCA. So you'd want to install all of the suspension, leave the shocks and the torsion bar adjusters out, and then cycle the suspension through its entire range of travel to see if you have any significant resistance or binding of the LCA. It can be an issue even with the factory strut rods because they were really a "one size fits most" kind of operation with big, soft rubber bushings to deal with the wide factory tolerances. But the stiffer poly bushings can exacerbate that, even when they're the right size, and obviously can introduce even more binding if they're not the right thickness.
