Ok, i'm looking at a set of 64cc double hump heads. The guy wants 100 dollars for both. I already have springs/valves that will fit them. The only problem is that i don't know exactly how to mount the alternator because pre1969 the accessory holes weren't drilled in the head.

I need either a solution to this problem, or an after market bracket that will let me use an alternator mounted somewhere other than on the head. I've heard of companies that make brackets that mount to the header and the water pump but i can't find them? Can someone help me please?
