[Healeys] Clutch Alignment Tools - AH100

[Bob Haskell]

John,

If I was going to make a set, I'd make them like yours.  The only other 
dimension I'd need would be the length of the pilot.

There's a firm (http://www.clutchtools.com) that sells them for $10 and 
their catalog incorrectly lists the same tool for all big Healeys.  I 
thought it might be helpful to see if they have the tools with the 
correct dimensions for the BN1 and BN2. Their tools are splined, so 
that's the reason for my questions.

Cheers,

Bob
