New windshield setup installation

[paddy]

I am looking to install the HD windshield and apron/cover setup on my 51 LE sidecar. Currently there are no existing holes for the arms or fasteners on the body. Was there ever any instructions or dealer bulletins printed to show locations and measurements for any of these holes for my installation? Maybe for a dealer installation?
Or is there any members that could supply me with this information from their FACTORY installed sidecar windshield assembly? Any help here is appreciated. Thank you, Paddy
