Help with 1939 D2 in International Harvester / IHC Posted April 25, 2016 The rear end is narrower than it should be. The engine motor mounts are in a different location, trans mounts are also different and the floor board has been cut so the sifter is in a different location. I hope to get engine numbers and other info so I can try to determine what engine and trans are in it. Any info on this is needed. I would like an org rig but I am afraid finding org parts is a lost cause. Next best thing would be a nice running rig with modern drive train.
