on my -6 cowl, the lower cowl bottom hinge pins have retainer clips which are not welded on, holding the handle end of the hinge pin and they screw in to the lower cowl with flush screws and a self-locking nut. Well one of those retainer clips went missing somehow. Is there a vans PN for this, it just looks like a folded over piece of aluminum large enough to feed the hinge pin through and a hole drilled in it for the screw. I looked at DWG 63 and I don't see a retainer clip for the two lower pins.
