so im doing some rust repair on my 68, and i am very new to rust repair and putting new panels on so any help is appreciated. currently I am working on replacing the inner and out rockers on both sides and the entire floor pan and toe boards. wondering if i should replace the floor first or rockers first? and if i can weld the inner and outer rocker together first and then put it on the car as one piece? and should i put some extra bracing into the car while doing these repairs to make sure the body does bend or twist in anyway?
