Bummer,
I am sure when they order "X" number of planes from a supplier they order "X" number of replacement parts. When it comes down to it $$$ control the business. You cannot stock spare parts for every type of plane produced forever.
On another note my friend did order and receive his parts for his Cessna 195 and it is back in good flying shape. The plane really fly's nice and looks good in the air.
Later!!
