Maurice,
I looked it up for you in an old Tweeks catalog I have in my archive here (vintage 1995) .
The part number in there for this distributor body is a 911. 602.022.00.
They also list 901.602.021.02 and a 901.602.201.50 as early 911 distributors. But they list yours as a 911 part#.
You will need a Bosch cap and rotor as well. You present plug wires will still work.
