Wayne and Gordon installing duct tape over the oil troughs and ports to keep dirt from infiltrating into the mechanism before final assembly. Grinding grit in the wrong spots would do nasty things to the newly-built shafts and bearings.

The bright steel stripe in the ring gear is the shim plate that acts as a filler at the point where the ring gear was milled into two halves, or as close as one can get when the gear is 41 teeth around.

Also note the approximately 1 1/2 inch gap between the cross box and the gear hub.....all but 1/8 inch of this space will be filled by a bronze spacer washer.
