Busy, busy couple of days.
Yesterday, I had the M5 brackets welded onto the frame rails and he found a pair of the plates leftover from an E36 kit that also used the Energy Suspension bushings, so that's all done. Then, welded the LR bumper bracket back together, so I could reinstall the rear bumper. Also put in new UCAs with urethane bushings (UBER MEGA AWESOME).
Then, I decided to see what was up with my drivers seat. The inner thigh bolster popped away from the frame, so I figured I'd need to have that welded. Unfortunately, there was a lot of flexing if I had the rear of the seat at any height other than the lowest, so I pulled the seat out and started disassembling it. Within 45 minutes I had it completely disassembled without leather, foam, etc and saw that the base cracked down the middle on each side. So, I took it in this morning to have it repaired and reinforced. Got it back around noon and started reassembly at around 5pm. By 6:30, I was happily motoring again and everything works perfectly.
Next up: Brake pads.
