The pinion is just a little too deep. I'd take about .002 out of the pinion shim. The coast side looks good, but the drive side shows that the pinion is deep.

Re: Good gear pattern?

Thanks for the input guys! It is my first one but I've been researching/asking folks I know for a while now. Not too bad, just takes a little patience!
