Scotty, I am with the University of Wisconsin - Platteville FSAE team. We are looking at getting a Taylor Racing differential for this coming year but have a few questions before we purchase it. We are concerned that tulips from RCV will not fit in your inner housing that come with the differential. I know you sell tulips but we are not sure if we can get custom splined shafts from RCV. Do you know if the inner splines on your tulips match RCV's half shaft outer splines? Also if we got the differential with the sprocket and brake rotor flanges would it be possible to get an additional side without the brake flange incase we don't run inboard brakes this coming year?
