Hello Everyone, I have a ‘22 Loco 48 which I absolutely love. The car only has 10,000 miles on it and runs like a sewing machine. The only thing is that the rear end is geared low and can only do about 45 mph with the engine wound way up. I would like to not have to turn the engine quite so fast and would like to change the diff ratio. Does anyone know where I could get a new ring & pinion gear set?
