Are there any proper hub caps available out there?

Are you looking for ones for 14" wheels or 13" wheels.

I have a set like this for the 14"

13" only fit 13" they are slightly smaller diameter than all other dogdish.

14 and 15 are interchangable with eachother.

Thanks, but it's a full cover I had on my last one in 1977.

Its not a great pic, but that is what I am looking for, thanks
