8&3/4 axle fitment problem

pressed the retainer to cover the tapered bearing & got 25.75" from flat retainer out to the spline end. OAL 52 & 5/8" (iirc), Moser measured it & said it was stock A body width
Those numbers are spot on for what I get. On OEM parts

Looks like it's pumpkin time.

I have heard of the button coming out and getting logged in sideways etc.

Good luck to you
