Are these Center Caps Interchangeable ??

[Katmandu]

I have a friend (in another state), that wants to swap Center Caps from our wheels. His has the Running Pony and mine has the Ford logo.

Does anyone know for a FACT (before we spend $$ on shipping) if these Center Caps will interchange ??

Here is his Center Caps...

and here are my Center Cap off my (10) hole wheels....

Compare these pics below....

It looks like his cap's ID is around 5 11/16".

Where as my cap's I.D. is around 6 3/8".

Kind of surprising huh ?
