I was considering upgrading from 30 to 35 spline stubs on my D60 since I have 44" tires and blew up a stub 30 minutes into my first run. The stub failure was mostly my fault since I was stomping on the throttle to find traction on a slick mud/rock waterfall here in new england, I should have tried another line. Anyways, are there any parts to convert my Warn 30 spline hubs to 35 spline units? I would think only the guts of the hubs change and I would be willing to bet warn would sell replacement parts. Correct me if I'm wrong. Wouldn't this be a cheap alternative to completely new hubs and also allow me to keep my stock 30 spline stubs for backup's?
