Has anyone on this board replaced the outer sills on their RRC? Mine have rotted so badly that the B pillar is cracking on the drivers's side. The floors seem to be solid up front with only a bit of rot in the rear around the wheel wells. Mechanically, she's as fit as can be with just a bit over 100k miles on her. So I want to do whatever I can to save her. Any advice would be greatly appreciated.
