I'm trying to put a LSD in my sprinter so I have my Cusco RS 2-way LSD, John picked up my T-18 rear axle for me on the weekend and I'm picking up a T-18 tailshaft when I go to Queensland. But when we pulled apart the T-18 diff housing to test fit my LSD we discovered that the ring gear is completely stuffed. So rather than just replace it I was thinking of getting one with a higher ratio.

Does anyone know what ring gear I can use that has a higher ratio?
