I'm restoring my 1956 Ford Fairlane Club Sedan and I've been told by several people to be careful when buying and installing door and trunk seals because they can be (1) too thick and/or (2) can be installed improperly, both of which will cause the doors and trunk to not close all the way flush with the surrounding sheet metal. I've tried to research this subject, hoping to find where to buy the seals that are the correct thickness and flexibility, and to find some pictures or directions for installing them. The packaged ones I've seen have a fold in the rubber that could be installed with the fold facing either inward on the door, or outward, but no directions as to which is correct. I know a lot of forum members have probably been through this before and any advice on what to buy and how to install would be greatly appreciated. Many thanks, Ron.
