VERTS ARE PRETTY HARD ONLY BC IF YOU DONT DO IT RIGHT THE CAR WILL FOLD RIGHT IN HALF BEFORE YOUR EYES. this is m suggestion. replace what you need to replace. cut out only what is bad. using a cuting wheel making perfect straight cuts. some people do it differently. ive seen people tack the new panel in place and cut through the old and new floor so that you dont have to play with any fitting issues. either way i would but the car in the air with jack stands all over it i wouldnt even touch vert rockers. id let a pro do it bc that is the main part of the car. | 
replacing floor, rockers etc. on '66 convertable
