I have a set of late model wheel pants that will fit a 1974 c172 and newer. They are in good condition. The two main gear pants have access doors for filling the tire. The nose gear has a round access port.
I have a set of wheel pants from my 1975 M model. When I got them with the plane they were still wrapped up from a 1992 paint job. I've never had them on the plane. If your still looking please reply to this email.
