Need help figuring out ring and pinion pattern - 9-bolt.

Hello.

I'm currently setting up a used set of 4.11 gears in my 9 bolt. Unfortunately it's my first time setting up gears, so experience is lacking.

I have tried various online searching, and I've read up on the subject prior to starting, but the pattern I'm getting is as far as i can tell a bit contradictory. On the drive side I'm on the outer part of the ring gear, tho, on the coast side i only get some small marks on the inner section.

Any advice on the direction to go here to get a pattern that fits the normal guides for adjusting a gear set?

Any input appreciated.

Re: Need help figuring out ring and pinion pattern - 9-bolt.

That guide was more detailed than the others i have found so far, and included the information i needed. (i will need to decrease backlash as a starter.).

Thank you for the help
