I am considering a 1947 oliver 60 RC for a project. It runs, but needs some parts.   What is it worth as is? Includes hydo. pump and manure scoop loader..

Needs:
-rear rims- 7 bolt pattern...
-side curtains, rear panels
-front grill, trim strips

Where can I find some rims with 7 bolt pattern?  any leads?  
thanks 
Alex
