Gear setup?

[Cr33p3r]

Who here can setup the gears in my 9 inch rear axle? It's my daily driver so I cannot leave it somewhere to be done, I would like to learn what all is involved in setting up the gears.

What ratio do you want?

There are a couple '70s F-100/150 trucks in the yards. They would have a 9-inch, most likely 31 spline, most likely 3.50 ratio, but possibly 4.10 ratio.

In any case, buying an extra 3rd member lets you change out differentials at your convenience, and swap them back if you change your mind.
