'76 J-20 spindle

[G-Wag]

I just tore down my axle this evening and the PO cross threaded the drivers spindle so badly that only one nut was put on, over torqued and came off in pieces. That said, I need a new disk brake spindle. The spindles listed on here are for '77-'91. What is the difference between the '76 spindle and the '77?

Bearing size, inner one is smaller than on the newer ones, outer is the same on both...

Thanks! I have a 44 from an '88 wagoneer. Can I use those spindles with the newer J-20 hubs or are the outer axle shafts different? I think I would need a different set of manual hubs.
