Look out on ebay, at ebay id sponmon, and if you are an ebay member make contact via ebay and ask if he makes GT6 valances. ebay seller Sponmon on
ebay is what used to be (or maybe still is!) NG Triumph Services (Ian Gittings) and he certainly makes them for the Spitfire, see his recent ebay
listings:-

for plain alloy

for powder coated version
In fact I suspect he supplies the club, as he certainly used to supply stuff like the clubs hub pullers, spring compressors and carb heat
shields.
From my experience Ian's stuff is always good quality and he's a nice bloke as well!!
