Speedway Book: "Gear-Torque" - useful?

Does anybody have the "GEAR-TORQUE" book sold by Speedway. The description says:

"Modified Flathead running gear and drive line instructions for 1932-48 Ford V-8. All the best gear and torque tips and suggestions from the experts, with illustrations."

I am interested in comprehensive instructions on how to rebuild a banjo rearend. Will this book help me? Any other suggestions for literature?

 

Anybody?

 

I have it......it is well worth $8........that's what I paid for it a while back.....

I have the original set of three, bought from Jerry Hagens way back when. I think the HAMB probably has more information in one day than these books would give you. But they were originally published about 1980, before Al Gore invented the internet. I doubt Speedway has updated them any.
