If you are going to direct drive one wheel with this gearbox, all you have to do is line up the shaft using bearings on your bearing hole. There are two holes that are slightly higher than the center of the shaft hole (by like 1/8") on either side of it. Hold or clamp the box in place, use a transfer punch (or drill bit if you don't have one) that is 1/4 inch in diameter to mark on the versaframe where the centers are, and drill it. Two bolts like this will hold it well.
