You can still run an adjustable lower arm with a bushing. I run them with a smaller bushing, and you can adjust it pretty far and everything still lines up. Here are the Toyota arms I make with an adjustable bushing on them.
I use a 1.5" OD bushing with a 1/2" bolt that Prothane makes. I aligned the Datsun I built that had a Toyota clip with these arms, and I used the lowers to adjust the caster. That way the upper arm had an even number of shims simply to adjust camber. The thing is, most alignment shops won't adjust your caster via the lower arm, because it requires more work than just stacking shims.
