Were the rear wheel Opening mouldings different for the RS cars as opposed to the Non-RS cars with the style trim option? I am showing part numbers of 7795063 and 7795064 but don't know if these fit both RS and Non-RS cars. Thanks for the help.

Don't know the part numbers but the rear wheel moldings for an RS are different than for a non-RS. It has something to do with the Rally Sport side molding.

Do you have a group number? it's usually stamped on the package by the part number? If so I can probably find it in my GM parts book

GR.12.116, thanks for the help, Bill D
