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.
