Nice work on your swap!

Thanks!
I've got about 500 miles on it so far and I'm very pleased with the results!
It is very quiet and smooth compared to the HO52. I think shimming the carrier bearing also helped with the NVH. I've got the trans and first shaft at 4 degrees down, the axle pinion at 4 degrees up. Haven't checked to see what the second shaft angle is, but it is clearly very slight. For those who say you shouldn't have the first shaft and trans in-line, it's really not an issue. It isn't perfectly in-line and only a 1/2 degree or so is needed to keep the U-joint needles spinning.
Handling is improved, likely due to the track bar rebuild.
It certainly takes the bumps better with the lighter axle. Used to be a bump at 80 mph would really kick the tail end up in rebound.
The brakes are bedded in and seem to work better than the drums as far as being able to modulate. There's a fine line between on and locked up with drums since they are self energizing.
Happy to report my wheel spacers are not causing any issues, no vibration. I did buy some PYO wheels (2500HD) at the swap meet last weekend and these would eliminate the need for spacers altogether. But, not sure I want to give up the awesome look of the classic steelies and caps.
Gas mileage is improved although I'm not sure what I'll peak at. Still messing with the transmission programming to get the shift points, tcc disengage and lockup right where I want it. Should have that sorted this week.
