Looking for measurements for 1966 Barracuda Formula S 14 inch wheels

I am looking to change out my 13x6 inch wheels to 14s but still want to keep the original look with correct hub caps (part number 2781554)
I am having trouble finding any information on the 14 inch tire wheels; how wide, spacing etc

Any help would be appreciated.

Also if anybody is looking to sell their old set of wheels and hubcaps I would be interested
