Moser 60
I was confident enough in the Dana 60 efficiency that I got 2 from Moser. One is in my Aspen Wagon that I planned on high 11's and low 12's with high 1.50 60' times. I got another for my Dart Sport which has a best 60' of 1.47 footbraking and detuned to consistent low-mid 1.50's with a 360. Has most of the better options with a 4.88 Pro gear, but it's not installed in the car. (Too bad you're not closer, but gear might be more than you need anyway.) If you have the correct gear, I see them as basically install and forget about it, besides basic fluid changes and inspections, just to be safe. Cover makes it easy.
Also keep in mind that when some lightening options are added, it will bring the weight of a Dana 60 closer to an 8 3/4" because going from a SureGrip to a spool in a Dana 60 will save more weight than doing the same in an 8 3/4. Same with beveling the ring gear for weight savings. Normally you don't need additional bracing on a Dana 60 as well. Unfortunately, I don't recall the weight difference when I did the swap in the Aspen. But around 40 lbs may be the number in my case. I had to make up the difference by adding ballast per class requirements.
