I replaced both Lower Control Arms (LCA) (1243303407 and 1243303507). For the most part it was straightforward. There were a few unexpected surprises. On the right side one bushing's eccentric bolt (2013300018) was seized and required cutting. I ended up replacing all 4. The ball joint bolt (1299901001) was rusty, and I replaced the bolt and the nut (910113012003) on both sides. Although they looked OK, I replaced both spring shims (2013210984) as well. My spring perches looked fine and rust free.
I bought a spring compressor on eBay from El Paso Tools, which is Baum Tools' eBay operation. The tool is superb and ships directly from Baum for about $200.
Here is a nice thread describing some of the work I had to do and was very useful to me. Especially with regard to the anti-seize compound and silicone paste usage. I loaded the bushings and the ball joint bolt with anti seize to ease installation and future adjustment and removal. I used Permatex gasket maker to seal the gap at the knuckle where the ball joint stud is. The manual calls for wax.

A relatively easy and safe way (if not the best way) to cut the eccentric bolt is by disconnecting the ball joint, removing the spring, then cutting at the front of the rear bushing. I managed to remove the LCA with one cut. I used a Milwaukee Sawzall with the foot fully extended. I managed to cut without hurting the car, scratching the finish. I found the 5712 blade to be the best for this. It is still a lot of cutting, rubber smoke, but it works its way through the bushing.
Thanks again for all who replied to me. Please see photos below.
