Door shields (clear Plastic) replacement 76 vette
The 'shields' you are refering to were made of thick plastic sheets. Don't know if anyone sells these 'pre-cut'. You can make your own by purchasing some thick plastic sheeting in rolls. Sometimes known as "visqueen" (sp). Cut it so you remain within the edge of the inner door panel, as long as you cover all access holes and allow room for adhesive application.
The orig adhesive was a strip caulking/adhesive. You can also dup this by using 3M's strip caulking (in black). When applying, o/lap the ends and keep it at least 1/2" inside the sheet. Clean the inner panel surface with solvent first for max adhesion. This will produce the water intrusion 'shield' that was orig installed. And inexpensive and professional solution.
Good Luck -Rod :chevy
