I bought a new left hand switch assembly as it was a narrow one and gave me the right amount of clearance around the clutch lever. I had previously bought another narrower one but it had really small wires and would have required relays to function correctly, so I bit the bullet and went with this one. It was fairly expensive, but had everything I wanted and was from a dealer I had used previously who was great to deal with. When it arrived it was exactly what I wanted, however the back part of the assembly was for 1" bars, with the front part (with all the switches) was for 7/8" bars. I fitted it up and it wouldn't tighten up on the bars, so I messaged the dealer and he was very apologetic and offered me an immediate refund, including him paying for the freight both ways. I thanked him for this but as the switch was perfect for my application I decide to make up a new back piece. The third picture shows the original one at the bottom and the replacement at the top, and it all tightens up perfectly.
