I'm about ready to order Warn inner and outer chromo shafts, and I noted that the outers for Waggies come in either 9.94" or 9.72" versions depending on if you have disks or drums. I always thought all 19 spline outers were the same. Is it just a matter of getting the c-clip on the end or should I be concerned about other differences? I will order the correct Warn units for my application, but I'm curious for keeping trail spares on hand.
