Welcome back, very few bodymen have the skills or patience to install a new doorskin with no bodyfiller, especially some of the aftermarket stuff we are stuck with on our cars. If your doors have minor damage that has been repaired I'd consider re-using them. If they have previos ugly repairs like Salmon has described then check out the inner framework carefully for rust, damage or old repairs before you replace skins. It may be cheaper to buy new door assemblys and sell your old ones. Just an option to look at. good luck. Neill
