Okay awesome, that's what I thought. It was owned by an older gentleman before. I couldn't imagine him putting aftermarket wheels on it.
Anyway, one of the wheels has a small air leak so I'm just going to buy the matching wheels off Craigslist. I wanted to keep the car mostly original which is the reason I was wondering about the hubcap but I'm not worried about it if these aren't the original wheels. Thank you for your help!
