I have fitted the rear wings using an AH Spares new fastener kit but ran out of fasteners for the last hole at the bottom of the wing. What type of fastener goes here? Is it a regular nut and bolt or a Speed nut and bolt like the others. Any D washers used at this spot?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Second question. Where the rear wing meets the B post it is fastened with a screw through a 1” x 3 ¼” tapped plate. The service parts lists call for a ¼” x 5/8” flat head (countersunk) screw. Is there a reason this is a flat head screw as opposed to a hex head screw? Will the hex head screw create a clearance issue for future parts?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks… Harold</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
