A few members saw my '72 MGB-GT a couple years back when I drove it up to Rockerbox in Milwaukee. This Winter I finally tore into the long needed body work.
So far I have replaced the left outer rocker panel, membrane (a vertical stiffener piece that runs between the outer rocker and inner sill), and a big chunk of the left rear fender.
Last weekend I tore into the right side, which is in worse shape than the left. I will end up replacing the outer rocker, membrane, part of what is called the castle rail (part of the unibody that connects the inner sill and outer rocker with the membrane sandwiched in between), and a small part of the right side floor and inner sill.
I will also need to replace the bottom of both fenders behind the wheel well, but that will wait until the sill repairs are done.
Here are some befores:
