Bad luck on the gearing problem, but those BM are rather quite fat, but the cooling fins are so cool looking its not so bad having to stick with a normal tranny and buggy ratio diffs. On the up side, if you did go to a centerdiff unit eventually, you would only have to change the ring & pinion gears on the front and rear diff to make them Pro/truggy ratio, much cheaper than a pair of new diffs.
