Cliff, I believe they are all 13's, but they look nice with the wheel covers in the trunk. The chrome, bent bumper and the rest of the grille is in the car.
The "long" lug nuts were (generally) only used with the wider 14 x 5.5 inch rims (Formula S cars) The 13 inch rim cars with similar though the wheel cover nuts used a shorter version... It sure looks like the longer nuts in your photo... and that would be cool if by chance they were the 14 inch wheels w/wheel covers!!! Check it out... & good luck with your cool score.
