8 3/4 posi unit change

I looked at my axle housing there isn't any adjustments on the right side on the housing just the metal seal but what I need to find out is if I put this posi track in it do I need to put the plates back on the rearend axle housing
You're not reading what I wrote. I said the adjuster will be on the right axle. Not on the housing it is between the flange and the bearing. If it is a stock Mopar tapered bearing.
If it is a green bearing it will have snap rings and plates and rubber o-ring going around the bearings. How about a picture so we see what you're talking about.
