Hi folks, I have 2 different 8 3/4 out of challengers, one with axle adjustor, one with out the axle adjustor. This leads to my question on the non-adjustor? Now you can buy green axle bearings to eliminate adjusting the end play. would the non-adjusting axle that i have be the same as these green axle bearings not in being same bearings but serving the same purpose any thoughts?
