Would 53 54 dodge hub caps fit a steel rim for a 1968 dart?

I have a 53 wheel and will try and check the cap diameter. the caps are held on by 5 tab like clips.

The tabs you're talking about are the ones rivited to the wheel, in between each bolt hole?

If so, my '48 Dodge uses the same setup. Those caps won't fit other wheels unless you add the tabs to the newer wheel.
