[Healeys] New Front Hubs

[Ed Woods]

Hello List,

I have two new front 12tpi hubs for my BN6 which I'm converting to BT7 disc 
brakes. The old BT7 hubs are fastened to the rotors with a splined stud and 
nut, the hub being countersunk to accept the taper at the stud's head. The 5 
holes in the new hub are not countersunk.

The question is: Do I have these holes countersunk at my local machine ship 
to accept the old studs or will the bolts as used on the late BJ8s fit?

TIA,

Ed Woods
