Hi Mattax,
sry for my late reply but this was lots of information and stuff to check on my side, but now I can give you the following update:
Radiator:
Is original. It has the same stamped number as on your pic: 38086. The other number is not readable anymore, but the radiator looks the same as yours.

Fan blade:
Is original I assume. I compared your pic to my fan, looks similar dispite the notch.
No fan clutch used, should one be in place?

Distributor:
Sry, forgot to take a pic. I will submit later, but at least I can tell you now that my new electric distributor has a mechanical advance of 22 degrees and an adjustable vacuum advance.
Cooling Issue:
Thanks a lot for all the information on the timing, but at first I need to solve the cooling issue and with this I have some other questions:
I took the radiator out to detect where it is leaking and wanted to inspect the water pump and thermostat.
There was no thermostat used AND the waterpump was short circuited. Since the heating was removed someone connected the outlest of the waterpump directly to the engine.
What shocked me most was the situation in the opening of the thermostat...lots of rust and rust-mud. I assume the water channels are jammed with this stuff.
-) Any suggestion how to flush and clean the cooling system best?
-) I read of citric acid and Bars Nural. What are your thoughts on that?
-) Should I just pull the freeze plugs and flush with high pressure cleaner? I do not want to completely disassemble the engine.
-) Do you think it is possible to get it clean at all?
Below please find the related pictures. Looking forward reading from you.
Best Chris
