Here's my story, I scored a new set of 240z doors for my 280 (not knowing that the male/female door catches were reversed). I proceeded to remove all the rust, prime and coat the inside with truck bedliner, install sound deadener, shaved the door handles and installed the poppers to open them. When I installed them on the car I suspect my neighbors 3 doors down could hear the profanities. Not wanting to start from scratch on the old doors, I cut and migged the old panels to the new doors. I was able to get it to work, the gap was bigger than I would have liked. It turned into a lot of work.
My advise would be to get the right doors and save the hassle I went through. Good luck
