Ok, I just got back from Napa.

I am really optimistic!
They look great! The cup side splines are not right, but hopefully that won't matter, as long as the balls line up.
The outer splines are correct and the length is correct.... so, crossing fingers!!!

I also am repacking the wheel bearings and replaced the rotors front and rear with drilled/slotted R1 Concept rotors and new ceramic pads.... also, new rear parking brake shoes and a good cleaning of the springs and hardware... they were coated with oil from when I flooded the rear diff and pressurized-out the oil/water through the axle seals to the parking brake area.
I'm stoked so far... hopefully done tonight with all!
I'll let you know.

Thank you for all your help and input!
