40 holes Eclipse front hub.

[Bertil Lindahl]

Restoring a 1913 Harley twin. Missing front hub. According to Harley parts catalogue they only used 40 holes Eclipse front hubs in 1913.
It seems impossible to find a 40 holes so manufacturing will solve this problem. Now my question. Have a hub with 36 holes but are there any differences in measurement between 36 and 40 hubs excepting number of holes? If so I would be very pleased to have info about this.

I have a nice original 1913 HD twin. If you need other assistance let me know. When I have the time to help I will do what I can. Right now I am busy building an HD 1912 belt twin for the Century Race at Barbers Motorsports Museum (100 year old bikes racing around a 2.5 mile road race course) and preparing my 1914 HD Cannonballer (The Gray Ghost) for the big event.
