Was Riverside early in the year? I ask that because Parnelli's car did not use that flapper fuel filler for long. Most pictures show the big aluminum lid with the knob on it. It also appears to be missing the two chrome marker bezels that they used as fuel tank vents above the stock gas cap location. The white part of the roof is very wide on this car too. Also has a chrome bumper, some were black but I think they put steel ones on the rear to balance out the weight. There is actually a factory light weight steel front bumper for sale on ebay right now.
