Kind of hard to tell but it is a straight, unbolt-bolt in deal. I did find a part number for the adapter itself but once again, it too is a long gone number.
I did not realize how long that shaft is. Compared to the stock Ford pump it is alarmingly long. However the tool to install the pulley puts it flush with the end of the shaft, which is where it needs to be.
