Fellas,
A former boss of mine was kind of enough to invite me to come pick up all of his left over parts from his 55 Ford Customline since he is retiring soon and sold the car a few years back. Among the goodies he wanted me to take was this adapter...

There were a number of parts and I quickly snapped a photo because I did not recognize the item (neither did he ). It is aluminum, 1/2" thick, and the four mounting holes on the interior are definitely Ford's 55/56 manual transmission case specs (and of course more years than that). There was a part number on the back of the adapter, obviously not Ford, but the adapter is buried in the trailer until I can get to it. 

Does anyone have any ideas?
