I don't think you'll find a GM part number on those. IIRC, they were only offered with the car from the factory or from SLP. I checked their website but they don't show them anymore...may still be worth a call.
After further research, 10951 for coupes and 10952 for convertibles were the part numbers from SLP. They seem to be about as rare as a football bat now.
