Well, after looking at the VX parts list that is available for downloading here, I see there are 4 different kind of clips for each inside rear panel. If you drop the first and last digit of the VX part number, you will have a GM part number. You can go by a autobody jobber shop, or a GM dealer, (dealer prices) bet you will find your clips, or you can order from Merlin and wait a week to a month if they are not in stock. Depends how fast you want to finish the job.
