Can someone tell me the differences between 43421-60012 and 43421-60013?
I thought it might be related to the length of the driveshaft, but I didn't have driveshaft specs at hand. If this is it, it would be nice to know which pair of driveshaft/flange numbers would work together (that weren't originally mated, that is), with a spacer added...Being the length the lockout hub hub body got shorter 1/79 the same time the hub flange part number change would thing it has to do with the length of the axle shaft and how the C clip fit. I know I have a 79 hub some where with flange and a couple of other fine spline drive flanges at another location but never compared them side by side.
