[ercoupe-tech] C85 prop size confusion

[mokied]

I have looked at the data sheets and am still a little confused on prop size.  
Can I put a wood 74 inch Sensenich with 47 pitch on a C85?  I see where it says 
in the data sheet for the original C versions of the coupe that you can use any 
wood prop with maximum diameter of 74 inches?  However, what if the coupe has 
been from C land to D land and maybe even CD land?
