I know this topic has been beat up a bit but I am having trouble installing the one piece plastic headliner I purchased from Classic Parts. Instructions are not included and the description only has this tidbit ** MAY HAVE TO TRIM SLIGHTLY DEPENDING ON YEAR **. Is 1950 a year that needs to be trimmed a little? Does the leading edge need to be under the windshield seal like the cardboard does or does the trim hold it in place?
I have only a handful of things left to do and this will become my daily driver so this headliner needs to just bow to my wishes.
