Mind is playing tricks on me again
I just found this hubcap ( no name ) but looks close to early Hayes or another accessory wire wheel cap
2 1/4" across
please see photo's, Bob
Bob, it looks like it would do the job. I have never seen one with that rounded raised section in the middle. Other variants I have seen have been plain, with no Hayes branding and plain ones with the Ford script stamped into the end on the INSIDE of the cap.
Allan from down under.
I have seen these before , but can not remember. where. getting old???
Sure looks like a Hayes without the usual graphics. And the flats on a Hayes cap is 8 sided like this one so . . . . What's the od of the thread measure?
