Problem Solver UCA Bushings or Not?

I put my order into Rock Auto yesterday, and I'm getting the problem solvers and the "improved design" strut rod bushings. The car's out at the storage barn right now, but the last time I set the camber, I put it near zero or maybe just a little bit negative. I didn't even check the caster at that point because there's really a limited range of adjustment in these old cars sometimes, and getting the camber about right seemed like my first priority. We'll see how it works out.
