The oval hole for the valve stem does indicate a trim for a 7" wheel in FGFs. 6" had open ended slots. Either those rims are built with an offset different than original, or the trims are just plain wrong. I'm putting my money on the trims being wrong, see how deep mine look compared to yours?
Lay a trim face down and measure from the floor to the inner rim.
