If you have no shims it will take a few tries to get the pinion depth right. Aftermarket gearsets have the pinion depth marked on them, for example 3.127, which would be +.002 (or .002 less shims) from the designed ideal depth of 3.125. Since you have none, a good starting point on shims is .035"

If it ain't broke ... you're not pushing it hard enough.
