Have a complete spica pump that includes mounted cogged gear and 2 wires for $350 + ship. A 1BB4CS75 T255/1 N 22244 so it might be a 1975. I know nothing about this as it came as a spare with my car and looks pretty good and clean.
I have no idea if it is in running condition. It came with a 78 spider that I just bought but it is clean and moves freely.The owner before me bought it as a spare along with a bare head and he included the parts when I bought the car.
