yes, do the rockers,( front cowl, and lower front rear 1/4 if needed) make the door fit correctly so the car looks good at the shows, then do the front floors then toe boards last.
since the rockers and inner rockers are welded to the floor braced that hold up the car, gettting the body level is important and kind of fussy proceedure.
