Just got a new repro expansion tank cap for my 67 S/B.
The markings on the top are almost there compared to the original:

But the difference is very apparent from the top, that brass peened over stud really stands out.

All that brass.
One good thing about the repro is that it probably works pretty well. And I can probably use it on the car, while I refurb my original (which I never had a problem with)
Having fun,
