Just in case I want to restore my 08 GT/CS back to original, I'd like to buy spare rear interior caps where the light bar is attached. The originals were cut for the tube pass through and attachement to the body/frame. Any idea of the part numbers for these dove grey pieces? Other than my local Ford dealer, who will charge full list price and then some, where would be the best place to buy these?

 

I was able to determine the part number for the RH and LH rear interior caps on the 'vert. If you need to remove the light bar to change your car back to stock, you will need to replace these pieces - see 31004 on the attached dwg.
