I had mine done a couple of months ago, had to send it to Oddyssey in Texas!
Cost me $50.00 for upgrade, new smoke shell, P&P all in,
not a bad deal, and it only took them just over two weeks to get it back to me (UK).
When I asked at Smart Parts in Bexley if they were going to be doing it they said only the factory were doing the upgrades.
So its off to Texas or stick with the A version
