Well, I'm presuming the glass panel can be fitting instead of the the standard steel one but possibly the complete cassette is required? It would be a nice touch and no rust.

I don't want to speak too soon but so far I'm not losing the S/C on sudden WOT. Still will need to do a good few more miles to be sure as I had nearly done 250 miles and no issues but then I let the battery go flat (don't ask!), so the ECU has gone back to relearn mode. When I clock up 250+ miles I'll know for sure.
