Well... I found out that the rear coil conversion is a royal pain in the you-know-what. Removing the air spring was cake, but installing the coil spring was another story. After removing the upper control arms, suspension level sensor, and sway bar end link, I still wasn't anywhere near getting that spring in there when stepping on the knuckle. I also broke my spring compressor trying to do the trick to compress the springs and install a chain to keep it somewhat compressed before installing, so that's fun. After getting annoyed, I threw in the towel for the day with about a billion interior trim pieces, suspension parts, tires, etc. scattered all over my garage.

I guess it's not a huge deal, though... since I'm removing all of this, I'm just replacing everything while I'm in there. Should have new control arms and swing arm bushing kit delivered on Thursday which is something I hadn't planned on doing until later. I'm also waiting on a freakin bolt for the cam oil line to come in since I lost one of them. Special order from Germany so 2-3 week delivery before I can install the second valve cover! ugh. The joys of working on cars.
