If my short term memory gets any shorter, I won’t even have thought about what I’m going to forget.

Re: radiator filler neck size and threads
They vary a little, but enough that they are not all interchangeable. I bought a new radiator and the original old cap would not fit. I had to buy the hexagonal style cap.
