FWIW parts....
 

If you register here you can receive 1 week free look up with addresses and telephone numbers. It does save some research when parts scrounging especially for Continental parts. You need the parts manuals but with so many Cessna FBO's closing and other aviation suppliers kaput this site has a very nice search capacity. Most suppliers will respond via email within a couple of hours. Or you can just call for a quick price comparison. After one week you will have to contact via email with RFQ.
