Ken, my ignition switch is on the right (Jan '69 RHD). Your point before about the position of the screw/bolt holes on the underside of the shroud lower piece is important I think. That and the overall length of the shroud. The distance between the two screw holes and the rear edge of the shroud (i.e., closest to the driver) was relevant in my case. They were very close. Some shrouds had them further down.
