Ok, here are some images of the job.
booster looks awful but it still worked. Unfortunately I misdiagnosed the check valve for the booster. Lesson, just because you have vacuum and you cannot pump down the booster, doesn't mean your pump is working and the booster is bad.
use a 13mm gear wrench to get that last bolt. this is a w126. It is a little hard to get your hand up there.

ahhh, room to work
Now to get that sway bar bushing. Easy now.

the old bushing was pretty crushed and rotted out in the hole. Unfortunately my clunk as I pull out of my driveway is still there. So far I've eliminated the lower ball joint, the brake support rod, tie rod, upper control arm, sway bar bush. One day I'll figure it out. Maybe a sticky shock or the spring scuffing on the rubber spring shim. No worries.
Okay, so there it is. Car brakes, shuts down.
