[Healeys] Bolt-On Wheels again

[Ed Woods]

List,

My 100-6 arrived today. It hasn't run since 1972, so I have a long road 
ahead before I become, once again, a Healey driver.

I measured the distance between two adjacent wheel studs and determined that 
the bolt circle is 4.5" One of the wheel manufacturers quoted a wheel with a 
B.C. of 5". Can anyone confirm either measurement??

Also, is there a 100-6 owner out there with a web site from which I could 
learn more about this particular series?

I have a factory manual that I bought in 1966 for my BT7. Is there another, 
different, factory manual for the 100-6? Any other books that I should have 
on hand that'll tell me how to orient each Phillips head screw on this car??

Thanks,

Ed Woods
