Contact aaron Crowl, he has several. In my opinion, they wont, the biggest issue is the input shaft, it dosn.t stick out far enough to get a pulley on it and we can't figure out a strong (machining) way to extend the shaft. It also has no neatural. On the plus side it is a wonderfully designed box, rball bearings everywhere and it is oil filled.
It's also a 3 speed (which is all I use anyway) and is a two key drive.
