beats me Zip, I just order 1 5/16 nuts and taper washers when I order CVs. I guess I could send a couple out for some testing. I just torque to 150 then the next slot and let them go. I do go to the trouble to hand fit the bearing spacers. every time I strip hubs I save the spacers and play with them getting just the right feel.
Heck I was out today picking up some 2.2 watt dash lamps when I stumbled on a Smiths 270 degree sweep mech. water temp gauge to match my 270 degree sweep OP gauge. Going to look nice in my three clock center pod.
