This beltline window felt kit is an important glass-area restoration set for 1971-1973 Mustang Fastback owners. Beltline felts sit along the top edge of the door and quarter window openings, where cracked, brittle, missing, or deteriorated pieces can allow debris into the window channel and make the car look unfinished around the glass.
With 8 pieces covering the inner and outer felts for both sides, this kit helps restore the proper finished edge around the front door glass and quarter window glass. It is a strong choice when rebuilding doors, servicing side glass, replacing weathered trim, preparing for paint, or completing a clean Fastback restoration.
Restore the beltline window sealing and glass-area finish on your 1971-1973 Mustang Fastback with an 8-piece felt kit for both driver and passenger sides.
