Mustang Dynacorn Door Window Regulator Scissor Extension Passenger Side 1965-1966
Part Number: M3690
Dynacorn Passenger Side Door Window Regulator Scissor Extension for all 1965-1966 Mustangs.
Dynacorn's door window regulator scissor extension is a direct replacement for your original. The scissor extension mounts inside the door and attaches to the bottom of the door glass and door window regulator. It uses a scissor action to help raise and lower the door window. This is a common part to replace, as it is subject to high wear from constant use.
