Mr. Schwiebert,

I need to tap into your expertise.  I have a 1961 Oliver 1800 A series with a diesel that is in need of rebuilding.  I have found a fellow with a supposed 310 gas from a 1850 that will go right back in.  Will the 310 gas bolt right back in with my clutch housing and sheet metal fit right again.  I did not know.  Thanks very much.  DAVID ALVORD
