I need some expert opinions to repair my 550 utility as this is my first Oliver.  I was carrying a load of gravel in my loader when I hit a bump in the road and broke my upper and lower bell/clutch housing into pieces.  

The information plate is missing from my tractor but I believe that it is a 1959 or 1960 vintage.  

Can anyone tell me what years and models of tractors use the same bell housing?  And do the casting numbers need to match for the replacement pieces to fit correctly?

I live near Burlington, Ia

Does anyone know where there are any for sale?

I'  Thanks for your help!
