Prop sources needed, 337G non-turbo

[chrisktx]

74 G model, non-turbo

Looking for leads on serviceable/OH props (already got quotes from MT and McCauley: in case you're wondering, in 2015 they're about $14k per end, new).
Already did the Controller.com search and left a PM via Controller (rarely works), voice message full (not a good sign), non existent website (not a good sign), very little on Google (also not a good sign), to Centennial Air Parts (Kansas)
Called Commodore, played phone tag multiple times, didn't get a follow up call...but will try again. *sigh*

This plane has the longer front prop (78")

Cessna part #: P3064229-11 (Front), P3074231-21 (Rear)
McCauley model D2AF34C306/78CAA-0 (Front)
McCauley model D2AF34C307/L78CBA-2 (Rear)

Looking for more leads to help in the search. Thanks!
