The Cooper S had these mouldings and this is the same item but made for the MK3 wind up window cars. These are easy to install, drill 1/8" holes evenly spaced on the straight edges,3 each side and 4 at the top(not on any corners)of the window frame. The moulding slides over the bottom 2 side rivets and snaps onto the rest of the special pop rivets on the upper edges of the door.
MS67 is for the RIGHT door,
MS68 for the LEFT door. See 14A9773/4 for MK1/2 doors.
