It's unlikely that its cut at 14.5*, 30* would more likely than not HAVE to be custom made, and a 20* pressure angle, commonly refered to as a Metric gear, is the only other reasonable alternative.

From what I've heard from people, though Metric gears are better for some purposes, I'm not sure if they are a step up in effiency though, and they aren't desirable because usually of a higher price, and a lesser availability, but at the size 968 looks to be using them, the price difference would be minimal I believe. However that depends on where you live (see Tristian's Response)
