Richard hit the nail on the head with that question. I have been told that #413 had a Ridewell solid axle and #416 had the Dana IFS. I am not certain about #414 or #415 although I 'think' #414 had the Ridewell straight axle. Of course it is very easy to tell if you look under the front of the coach.
