Thank you.
It might be that 'stupid is inversely proportional to how long you've owned the car. I was probably more careful in the beginning when I couldn't afford such a mistake, but after 42 years of owning the car and doing it all myself, I did not build the motor, you get to relaxed. If I didn't have Webers hiding the damn distributor it wouldn't be such a task, but they are so beautiful. Now I have to do everything by feel because you sure as hell can't see back there.
It occurred to me, I do have one idiot light for the manual fans.
