8.25 solid pinion spacer.

pinion bearing solid spacer Ratech 4114 is correct for the 8 .25 rear axle --- why you have a crush collar for a 489 case 8-3/4 rear axle in your 8.25 is the mystery ,obviously someone screwed up in the past--- you should have had a simple collar of about .440 - .450 crushed length

Thanks John. I got a reply from Ratech saying it sounds like I am working on 8 3/4 not a 8 1/4. I do know the diff on these diffs. When I tore this apart it looks Virgin never apart. Guess I will just order the 4114 and see what shakes out. Only $14 at summit. Did Mopar use a spacer Akin to the solid ones used on a 741 case to take up the room between the bearings then add the sleeve? FYI this has 321 gears open carrier.
