Is there anyone that has installed the main door W/S on a 1960; using the current repro w/s? I have black, hollow plastic plugs under the door and up the side; at least as far as I can see without taking off the current weatherstrip. Does the new W/S have wires or pins that snap into the plugs? What goes into the two small holes on the flat part of the door in front of the door post? I searched the Archives and looked at every W/S article on the NCRS disk; no help.
