Engine mount bracket, 318 mid 80s D250 4x4 pickup truck

Is this the one that can be used as a "conversion mount" to install a 360 into a /6 K frame?

This mount is the OEM driver side mount from my friend's 318 truck. The separation of the ears on the block is wider on the 318 so won't fit unless you add some washers or spacer to make up the difference in the separation to fit the 360.
