Couple of things.
1. Why did you not get a high pinion diff since you got the whole thing new?
2. I always bent the tabs over on the first nut so I can torque the second nut without moving the first nut when doing wheel bearings.
3 Do not throw the stock trunion pins or bearings away, you never know when you might need them. Or you run into someone on the trail that might need them. Keep them in your spares box.
