I was recently starting to restore my 1973 Mercury Cougar XR7 Convertible when removing some rust three large chuncks fell out from under the Rocker panels. Now these chuncks where not repairs but coverups held in place by undercoating and caulk. If I could find the guy that did this I would have a few choice words for him. Upon further inspection the car has little to no remaining bottom surface remaining along the bottom of the rocker panels. The outer Rocker Panel seems to be soild and whole. The inner is missing in spots from what I believe is the lower weld up to an inch above the inner floor pan. My Question is I have no idea how the structure for the car is at the rocker panels? Is it only a inner and outer rocker panel or is there a frame rail running between them? If it is a frame rail what is the best way to make this repair? Can I buy inner rocker panels and or a frame rail for this? If someone has a picture of what the structure should look like? Any Help is much appreciated.
Thanks
