I had a bottom overhaul done on my PA24-250 Comanche recently. I have a McCauley 3-blade prop on it. My mechanic says to be legal he must install the McCauley STC Kit under STC number SA00773CH which includes the 4 new motor mounts (part number J3804-42). First of all has anyone had to replace engine motor mounts with the new ones and second does anyone have any idea where I can purchase the new mounts part number J3804-42?
