8 3/4 diff

You betcha! I'm getting out some shade tree mechanical tech to the general public. Who really cares about some f'ed up, used gear; we only want to deposit in bank of mechanical knowledge. One may not have access to 280 ft/lb, air tool, or the solid spacer, in time to get to the track.

Not going to the track, just want the noise gone, I don't think it is very good for he gears
