I need some help. I just picked up a Quaife QBE62G for use in an RCR40. It is still in the original crate. The seller did not know if the final drive is 3.5 or 3.75. There is no label as far as I can tell. Does anyone know how I can determine the final drive ratio other than by contacting Quaife. I feel bad about contacting them since I bought the box second hand.
