Let me rephrase the question.

There is a tranny sitting on the ground, not attached to a car nor is there an obvious way to figure out what it came from. The sticker identifying it is legible however. It does read NV T-350, then has many other numbers. My question, what should I look at (on the tranny only) to identify it as the 3.55 final drive?

Your info was helpful in any case. Just I don't have the car to look at.

Built block.
Refinished head.
Tuned suspension.
TURBO.
