You can thank passnb4U@aol.com for the post on setting the pinion angle. I
found the original in my archives. I'm not setting the rearend angle yet, so
an approximate measurement won't hurt me any. My truck has zero weight over
the rear wheels; no bed, no doors, no seat, no gas tank, no glass, just a
frame and empty cab. But I need an approx. measurement so I can set the
transmission angle.
