Thanks for the tech, much appreciated. I didn't really give up on the axle, I bought a set of Rockwells and going bigger than I originally expected.

However I am not interested in shipping this axle. Sorry.

I think I saw you did some research on that axle for a while, did you give up?

Any how few quick questions on tech.

450/550 had stock 35 spline outers. Is that why everyone sells 450 unit bearings, All they do is redrill stud patter.

450/550 are longer on each side by one inch?
The knuckles have bigger brakes with a bigger caliper mounting locations

450/550 have the bigger metric lug pattern than F350, which would be good for having more meat on hub flange for redrilling

450/550 all have dana 60 HP

How much for shipping 84104
