Jeff,
US Specification was usually for the 49 or 50 state emissions requirements, required sidemarkers F & R (adding F "Warts" - because R were integral to the taillights on all models Worldwide IIRC), & anything else US-DOT required for that MY. Some MY's also had the CA Spec. for the more stringent smog controls here.
As for the "... w/Sun Test Special Paint" part - IMHO the COA person either misread the Porsche Code or used the wrong MY &/or P-car model's option code - as they do all too often!
Look at other COAs & Window Stickers at Jeff Bowlsby's website to see if you can find what the correct info should be instead of that "... w/Sun Test Special Paint" BS.
