Inner wheel bearing and seal spacer

Anyone know why the driverside wheel bearing assy would have a spacer on the inner seal but the passenger side does not? When I pulled the hub and rotor apart on the driverside there was a spacer that was inside the seal but there was not one on the passenger side and I have no idea why or if one of these is wrong. Anyone? It is a 1983 B2000.

The beveled center piece in this pic is what I am talking about. It is not on the passenger side.

Off topic of that cause I don't know the answer but where you get your grill from? Mine is cracking etc. I'd like a phantom but nobody makes them anymore.

The grille on my 83? I got that off ebay if I remember right.

passenger side still stuck on spindle? or maybe part of the old bearing when they were last redone?
