I like the larger one posted with rubber and partner shown above.
Restoring Stainless caps over the years has,shown a single hole drilled in them.
Not sure what year's did it but gave seen it on some and not other's.
I just know some have the hole and was,factory.
Here's a tool for single hole
VW did the same but 2 hole as well as other brands who did the same.
Just an example or two so you understand how easy it also works.
Have seen these for buck something the VW has 2 holes
