Why not use adjustable lowers with some sort of spherical in one end that isn't a rod end? Pay attention to making even adjustments side to side, else you'll change the thrust angle.
Clunking is likely to happen when the inner sleeves that go through polyurethane bushings are shorter than the poly. You don't get full clamping out of your tightening torque - quite a lot of it can be wasted compressing the poly, and as soon as the suspension moves under accelerating or braking load, the joints you thought were properly torqued (but don't have the proper clamp loads going through the metal parts) slip a little until the bolt holes bottom out against the bolt.
I've been running LCAs from Currie in my '08 for several years now, which feature Johnny-joints on one end and poly on the other. They haven't been noisy under any circumstances, no squeaks, no clunks. Couple times a year I shoot a little grease into them (like at the beginning of track day season, for one). I did DIY-mod the poly slightly.
