I need some help with this one! Seems I have a barn door (drivers side) that should have the square hole for the door switch to mate up to the body side contact plate. I have a set of replacement doors all prepped, painted and ready to install but the driver side door I have only has a round hole where the switch square hole should be. I have searched various sites to see if a later or earlier model had a round switch but cant find anything to explain why there is a round hole. Any help would be greatly appreciated. I considered cutting the square hole but I think there is also a reinforcement plate in the original door. Thanks for any help.
