Wow, they look like fantastic value. How would you get them on the Triumph or Reliant hubs though? There isn't much information on the site about PCD's, adaptors etc. Looking at the pictures I guess they're Jag five bolt or Jag large splined fitment only.
I suppose it's possible to have the hubs/drums redrilled to suit, or a set of adaptor plates fabricated. Worth thinking about though - although I'm happy with my MGB wires my original intention was to find some Dunlop replicas, but I couldn't find any that would fit or were in my price range of cheap as chips.
Great find though.
