Need Intake for 1963 Oliver 770 Gas.  Head Numbers:  100334A and 185502B.  Block Numbers: 18220F and 104806A.  I would give part number; however, wife just finished cleaning house and I can&#039;t find the manual.  This is not the &amp;quot;common&amp;quot; manifold.  The distance between centers of the end intake tubes is 17-7/8&amp;quot;.  I&#039;ve been through this before and I saw a lot that were 3/8&amp;quot; too long.  Also interested in the exhaust (usually a set &#039;cause you can&#039;t break&#039;em loose).  I kept this one alive for 4 years with nickel rod and hi-temp silicon.  The side of the box finally cracked out completely.  Thanks for any help.
