Going to try and tackle it again this weekend. I'm assuming I'm going to have to keep shimming it out and adjusting backlash, then checking the pattern.
I would be happy settling for a non-perfect pattern, just trying to make the best out of what i have. Got a really good deal on the front and rear gears, and the right carriers (original was toast on 14 bolt)
Also had machine work done to 14 bolt ring gear and didn't want to risk screwing up a new one.
