PCV Valve needed for '63 R1 Where do I get one?

[JLB]

Using a 30 year old plus, NAPA Part number 2-9267 , I tried to buy a new PCV valve for a '63 R1 engine. NAPA said the number was still in their system, but no other information was available. No pricing, no inventory, no application etc.. Also had a Fram number FV 125 which did not come up in their system at all.
What is the correct part number and where can I get one, without going through it being shipped to me.
Thanks
John

In the past, I have referenced a brand X of a similar displacement and it worked fine. Just determine if threaded or push into rubber grommet.
