Apologize in advance if this is already discussed, just couldn't find it.
1.Are there any inner or outer dust seals on the rear hubs for my make and model?
2.Does anyone know good part numbers and if they are still available?
I have seen various posts addressing the parts listed below but believe they are for P2 or later. I know my bearing is a sealed unit on both sides but am unsure if there was a dust seal originally or one as a result of a service bulletin.

31360326 or 31340664 plastic ring (common RH/LH)
31329228 splash shield LH
31329409 splash shield RH
8624203 grease

Thanks in advance.
