Today's update:
Got the rear cargo area back together, with new(used) carpets and plastics, and re-covered speaker covers. I used a nylon 1/2" spacer under the rearmost screw holes to give some standoff from the subwoofer surrounds.
Removed the original lower front air dam, it was in really rough condition, installed new aftermarket unit. Fits well and looks good.
Did some major degreasing of the doorjambs. These things were filthy. Some rags and simple green, and they're presentable once again. I should have taken a "before" pic but I forgot - take my word for it, there was 20 years of grime and grunge built up there.
