setting the lash in 8 3/4

This is the way I've set them for 40 years and is the way Yukon Gear explains to do. Take almost all the play out of the ring and pinion. Then tighten the side that pushes the ring gear away form the pinion to get a backlash of .006-.010.
You need to have dial indicator and a magnetic base to set backlash.
I think I can get my hands on a magnetic dial indicator. So you're saying tighten one adjuster to push the ring gear to zero lash on the pinion. Then tighten the other to push ring gear away .006-.010 from the pinion, while not moving the the first adjuster at all. correct?
