I know a guy in Brissy has a really sweet disc brake front end model one, I think its 85 or newer, restored and hardly ridden, he is 60 something bloke that is a bit fussy, so its a good resto.
He was only talking the other day about selling it, as it just sits and he is buying a new 250 2 stroke KTM freeride.
I can call him and see if its OK to give you his number if you like.
Send me a PM.
Cheers
Kim
