Looking for disc front hub for '76 R90/6

[Zwicky, Eric]

Hi all,

I hope cross-posting is OK, forgive me if not.

I'm looking for a front hub for my '76 R90/6, takes a 17mm axle.

Let me know if anybody has one they'd like to sell, or trade for one I 
have that takes 14mm axle.

Thanks in advance,
