The 48-53 truck bellhousing has the mounting ears that I know are the same as my 37. 55-7 car bellhousings also have mount ears on them,and I think all trucks have some kind of mount ears on them. Even my 67 C-20 had them too but as you know the later ones wont work. A local junkyard is loaded with 48 to 58 trucks if you need one
