99% positive the rear main seal is leaking, not the pan gasket, seal probably hard as a rock on an original never rebuilt 50+ year old engine. Very difficult to change out with engine still in truck. There should be a rectangular cover plate in the open area. They are often left off or lost after a clutch job. This is what it looks like and may very well be correct for the 230 250 also https://www.ebay.com/itm/1956-62-CHE...JZGf1X&vxp=mtr
