I think I'm going to go check local yard, see if any frontiers happen to be around. If the cars are too close together i can pop both axles and drop the third meber to count. Figure it won't be that bad as there probably won't be many frontiers in the junkyards. I had to do this same thing looking for f-series length 28 spline axles for a ford 9". They aren't exactly common (or desireable), but there are tons more 9" equipped vehicles in the yards than frontiers. Spent probably 8 hours with a slide hammer in my hand counting splines before i finally found a set.
