Tony, logic has it that I have one of those swingarms but have moved house 4 times since I put the bike together. I found forks, lights, the bottom triple clamp and instruments in my shed tonight, but I have a feeling the swingarm might still be at my Mum's place 600km away. I'll be able to look for it there in early March.
The standard, perfect tank I gave to Barry Graham (bike wrecker) in Townsville for generally being such a great bloke while I lived up there - to add to his collection of odd-ball fuel tanks on display.
Regards
David
