I had Aquafina build my trans too. Took a long time to receive it as well.
1.083 1st gear
MFactory LSD
Mfactory 4.9 final drive

It's not bad to drive around, spins 3600 at 70mph with my street tires. But it's probably too short for most people. I had the trans built to trap around 116 at 7600 in 4th gear because that's all I want from my car.

I'd go with Bone next time, because he seems to be much quicker in his turnaround time.

For your question, I would definately get an LSD before a shorter final drive.
