This is not a recomendation. Just one source! McFarlane supplies these to several other companies for resale, such as Aircraft Spruce and Chief Aircraft. Contact McFarlane with aircraft serial number before ordering. This particular repair is legal by included STC (in the U.S. only. I don't know about Canada). Cessna MAY offer something similar not requiring STC. I would check, first.
