Will, I realize this is a really old thread, but I'm hoping you are still involved and have some info for me. I have an Interpart LiftLouvre from 1982 but the locks broke while trying to unlock them, so I've had the louvre off the car for a year and now can't find my key either! Did you ever have success fabricating the locks and keys for the two club members? I'd be very interested in buying a set from you if you did! Best regards, Eric Derr
