gear and pinion set up 8 3/4 489 case

Just got done with mine, Had a heck of a time trying to get it set up. No matter what I did I couldnt get a good pattern onthe gears. Come to fing out thepattern compound I was using was too thick or something, I bought a different thinner compund and was fine after that. But overall it was pretty easy, just wish I would have known about the compound before I pulled the diff apart about 20 times!!!
