Thanks. I ended up about .0085 +/- a little. This was my first fit so the prop shaft is not installed. It made it a little difficult to lock down the pinion gear, but it's within tolerance. The wear pattern looked good so I am off to install the prop shaft and hopefully a full differential. Once that's all in I will do a final lash check as I can lock the pinion by temporarily installing the trans yoke and holding on to it.

A side note, I had not noticed some of the info in the printed directions that came with the gear set. The directions that Chev's of the 40's provides with their gear set are the directions from Patrick's.
