In my pile of treasures/junk I have run across lower gear legs with 2 different lengths of axle. The axle itself is a different length and the part of the lower gear leg that the axle slides into is different. Does anyone know if the 14-13-3 Cruisair , or the 14-19 has axles that are about 1.5 inches shorter than a 14-13. The tire sits much closer to the gear leg on these lowers. I am thinking that this might be a change that started with the -3 Cruisair. Bellanca paperwork leaves a lot of questions un-answered. ____Grant.
