Yes that's correct. I didn't try to zero the dial indicator. I just set it to read and then took readings at 90 deg intervals by turning the crank. Top to bottom absolute figure was .0012. Left to right was out .0040. Runoout would be half of that figure or .002 in and .0006 in (.001 rounded for all practical purposes).

After posting I realized I had not put in the adaptor ring in the bellhousing that the Toploader requires. I re-ran the figures with the adaptor ring in and they didn't change much althogh the ring was very slightly elliptical I found out by spinning it around in the opening and reading the stationary dial indicator.

Keith Craft was to dial everything in but I'm not too sure they didn't forget so I thought I better double check it.
