Hi Jordan,
I
think Andy Nienhagen may have them ...
But be aware: the plastic bowls have/had a reputation for splitting, leaving you stranded by the roadside. Tony Brancato changes them as a matter of course, fed up with having to go collect people ...
Might never happen to you, of course

. There was a guy on the Motogiro this year with them on a '77 Darmah - and yes, he made it round!
Ciao
Craig
