Did you measure and record the backlash before you ripped it apart?

Used gears are tough to set up, helps if you've got a record of how they came apart.

Detroit Truetrac
The Detroit Truetrac is a helical-gear style performance differential that maximizes wheel traction and enhances driving and handling characteristics.

Operation
The Truetrac operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel encounters a loss of traction or the terrain changes, the gear separation forces take effect and transfer torque to the high-traction wheel. The helical-shaped gears mesh with increasing force until wheel spin is slowed or completely stopped. When the vehicle exits the low traction situation, the differential resumes normal operation.

Performance
Operation of the Truetrac is smooth, quiet and automatic. The unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning less time in the garage and more on the road.

Here's a link to a g80 3.42 10 bolt chunk, gear and pinion gear. They came out of a 94 z71. Everything appears to be in excellent condition.

SOMEBODY tore out the differential and pinion pictured in the first post, and if they didn't bother to record the backlash before they did it, someone is going to have a hell of a time getting it set-up properly.
