Possible to get bigger spurs?

[simplechamp]

Is it possible to get bigger size spurs for the Slipperential? I would love to get one but I can't use the smaller spurs that come with it.

The Caster F8T truggy has a stock spur size of 62T. The F/R diffs are geared at 43/13 which is already higher than most truggies. As it is I'm already going to have to gear 62/12 with a 1700kv motor. With a 50T spur on the Slipperential there's no way I could gear the vehicle properly.
