Just a follow up question on the subject... when did Ford stop using the centre with three tabs to hold the hub cap and the center looks as this picture (like the one with 1963 date code earlier in this post) and when did they start using this other center part with four tabs and another pressing between the lug holes (next picture)? I think this may be in 196...8...?

The images attached with Claes post speak some of what I write below, but not all. The 1st image is a "drum brake" style and the 2nd is the 69?-up disc brake with a larger center hole too (somewhere in the 70's? Ford went to the larger center hole, memory not clear on that note)
I can not give any date, but it seems that by like 1969 Ford had switched out to mostly the "all disc brake" version of the standard wheel. Going off memory, after Ford started selling disc brake vehicles, Ford was using a different wheel for "drum brake" cars and another version for "disc brake" cars.(presumably Mustang also). I am not cross-checking this knowledge with the Master Parts catalog but maybe somebody with easier access to the catalog might be able to confirm what I am writing. (I am writing this from memory). Hollander Interchange is listing for the O.P. of this thread two possible wheels. a 14x5.5 wheel and a 14x6 wheel. Quite possible that is how to identify the "disc" or "drum", I wouldn't say...but I DO REMEMBER disc wheels were different and could be spotted with a trained eye. Since the O.P. has "drum brakes" I would almost assume he should have the 14x5.5 wheels.
The 4-tab type would likely be one of those indicators, and the main other indicator (using my old "junkyard knowledge") was the curving between where the dog dish hubcap locks onto the tabs & where the center of the wheel meets up to the outer ring of the wheel. Disc brake versions were more "flat" in that area while drum brake versions were more a"rounded" look. Disc wheels would fit onto drum cars, but not vice-versa. Later versions would fit all and eventually, Ford switched out to a larger center hole that would also fit onto Mopar products. (There, I now purged some of that "useless knowledge" that was locked up in the vault/brain) Hopefully this could help spur another member to give the the Original Poster in this thread a better image of the exact wheel he is looking for. I think the wheel cover issue has been nailed down already but Yes, I remember the 68 Mustangs with their own version of the dog dish too and waited out on that reply.
