It was warm enough to take the rear end outside to clean this weekend:
After cleaning, I inspected the rear-end and found a couple potential problem areas. I asked about them in this thread on NastyZ28.com and it shouldn’t be a show stopper, so I can continue with the rear-end rebuild.
I also played around with getting TV streamed to my iPad in the garage while I worked this weekend.
After removing the seam sealer:
Main goal is to get the shell primed and bottom floor & firewall painted before it gets too cold again. Then work on the suspension.
