70 duster doors on 74

Thank you v dart...though I think you may have misunderstood...I have a 74. I just got 70 doors with windows and the whole 9 yards....what I am doing is just putting the 70's as in on my 74....I converted my front end to a 70 and my rear bumper to a 70 now if it works I should also have 70 doors....next I will be replacing the sails and rear panels....already have rear panels
