I've got a brand new Cessna door panel, part number 0415031-24-532 for sale. I believe it fits the M model but I'm not sure as my parts manual is specific for the earlier planes. It is listed on eBay
http://www.ebay.com/itm/331548650946?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649. If a club member is interested, I will sell it for less than advertised. PM me and we'll talk.
