I have read through the cancer support thread and I think I am ready to to start the surgery on my 72. From what I have seen so far it looks like I have outer and inner rockers to fix, as well as the floors. I also peeked at the front floor support, and it looks like it needs to be replaced too. I think the rocker boxes are solid, so I am going to try to not remove them. If I leave the top on and the rocker boxes in, do I need to brace across the door before I start cutting? I'm thinking I should be ok without the brace. What do you guys think?
