Question:
Can you confirm this is the correct orientation for the black rubber grommets (Center-Right) as assembled or should they be the other way around?

Thanks for your help.
Answer
Dear,
This is the correct orientation for Sealed Stud Assemblies with HHSSGR

Not sure, where you get these rubber ones from? (orange circkeled)

Also the white extra seal looks to be something special, looks to be polyethelene,
Not sure if that will provide you the objective of having a sealed fastener.
