After looking around on the Early911Registry, the lights that I have look very similar to the US version except, the city light hole and the placement of the adjuster screws. Mine have screws at 5 and 7 o'clock, while the one pictured
here and the others that I have found have one at 2 o'clock and the other at 7 o'clock. I have read several places that the lenses are interchangeable with several other models including 356 and VW's, but the buckets are not.
I have included an overall pic of the bucket disassembled for reference.
