This is from the HAMB thread referenced, he is using Ford 9 inch and 8.8 inch specifications as a "similar to" for his values.

"Not being able to find any preload specs for the diff preload I used the preload specs for a pinion bearing from some Ford Motorsports read end instructions. With new bearings I was shooting for a number between 16 in lbs and 28 in lbs. I needed to take more shim out. Took the top bell off and removed the .005 shim gasket. And the left the two .007’s Bolted the bell back on and came up with 22 in lbs of for the preload on the diff bearings. That sounded good to me."

Somewhere else he refers to using Ford 9 in and 8.8 in rear axle values.

VanPelts numbers should be good but it is interesting that his is the original Ford spring-scale values now being used as in-lb values! The original Ford specification was 12 to 17 pounds.
