I am using a heavy duty coaster with 12ga spokes, so I needed a bigger bolt pattern, to make up for the thickness of the spokes
the occ has a large spoke flange as well
So the measurement they are looking for is the outside diameter of the spoke mounting flange on the left side of the hub. I will have to ride over to my father inlaws to borrow a good dial caliper to get the measurements asap! My sons engine kit arrives on Wed so I will need to order for both bikes for sure! Thanks for your help Bill. I looked at your site and the bikes you have built there are beautiful to say the least! I am seriously considering a cruiser frame build after my sons mountain bike, he thinks they look silly and are for old folks. I am not getting any younger and I am so hooked! I spent my evening making a custom rear engine mount with some 1/4 in aluminum i got from the scrap yard today. I see many evenings under the halogens in my future!
