Would these work?

There are at least two AAM 14bolts in the left rear of the picture.
They were available in 10.5" on the 6.0L & 11.5" on the dirtymax trucks.
If you can use a squarebody or 67-72 axle in your 63 you can use a T800 axle.
3.73 gears are easy to swap into a 14bolt. No shims at all. The pinion housing bolts into the nose of the axle so you assemble the pinion in the pinion housing and pick steel gaskets between the housing and the diff housing to set the pinion depth. The carrier bearings are set with threaded rings.
