I'm overseas so can't do hands on stuff. Coming home on vacation and had a nifty little idea to buy an Olds hubcap and use if for an air cleaner top. I understand might have to pull off the mounting tabs. Whats the actual diameter of a 14 or 15" hubcap? What about a flat enough area for the filter to actually make a seal? thanks

was thinking of this one. Same year for my car and in good shape.
