I need a part for main gear on 1966 M20E.  It's seems to be called a dust-cap or cap-hub, the cup that covers the wheel nut. It has 3 flanges for attachment to the wheel and a tapped hole in the center for the attachment of the "hub cap". (I am at home and the parts manual is at the airport, I'll check the part number tomorrow if necessary.) I've sent an email to Lasar tonight, looked on Ebay, and checked Aircraft Spruce. Anyone have other suggestions?
