			i forgot to just look on 700r4.com
 they have a speedo calibrater majigger...i put in my tire size and the rear end ratio and they tell me what tooth drive and driven gears i need.
 
 looks like a 15 tooth drive gear and a 40 tooth driven gear.
 Now I'll either buy them or do what Tim said and get 'em from the junkyard.
