That is correct. You can still see some of the cardboard under the screw. Who got the metal ones? Based on assembly location?
Do you think based on what you know the motor may not be original? I had no reason to think it was not original. Every piece was completely shot.

rohrt, according to the '66 MPC, both motors were used in '64. Your p/n was carried forward to '65 and beyond per the MPC. Mine was only used in '64.
I know the metal shield vs. cardboard shield has been discussed here some years back but I don't recall if anybody figured out the reason for the two different units.
If not for the MPC I would not have known that the shield was specific to the motor p/n.
If I was guessing, I'd bet the early cars like mine got the p/n 5044573 with the metal shield and at some point, possibly for a cost saving, later cars got the p/n 5044586 with the cardboard shield.
I also wondered if the port location and wiring location made it easier to install at Assembly and could have been the reason for the change.
I see yours shows T-12. I believe this is a Date Code. Mine shows T-7. I'm guessing T means 1963 and the number represents the month. Mine would be July, yours December. My car was built in Nov '63 at Fremont. Unless we get tons of additional data, I have no idea what to make of that.
But for sure, I would believe yours is the original motor as I am equally sure mine is original.
vidguy, not sure if Dennis Ackerman would still rebuild cylinders, a Google search says he is now 79. But I did find this:

Says, "Hydro-Lectric pumps - a specialty".
I considered trying to replace the external seals on mine. But from what I determined, there was no way to disassemble them to check them internally. Seal replacement would not "fix" internal leakage which would make the cylinders weak. I kept the originals but decided to go with new ones. Didn't want to risk having to replace them later. I suppose I could have tested them and perhaps they would have worked as is. Maybe one day I'll try doing that.
