Dynacorn's driver's side door skin fit my door almost perfectly. It only required trimming in one small spot about 3 inches long. Take your time and work the metal slowly. Don't try to bend the flanges all the way over the first time around the door. I go around the door 4 or 5 times bending the flanges about 15 or 20 degrees at a time. I got very good results with very little body work needed.
When restoring my 65, both doors got new skins and required minimal alteration or work done to them. I have been a auto body worker since the days these were everyday cars and these skins are the way to go
