BN1 wheel stud size - wheel hubs

["Alan Seigrist Blue 100" <healey.nut@gmail.com>]

Hi -

I am looking into doing a redesign of the rear axle hub on the spiral bevel
axle (my wife's father has a couple big CNC machines in Slovakia) and I need
to know what is the BSF threading and stud size on the rear axle hubs (it's
the same for the front too).  I want to work out the threading and size so I
can tap the studs.

No promises but I get this set up and no one will ever have to deal with a
screwed up BN1 rear axle again... maybe even racing might be an idea.

Thanks,

Alan
