CUTLASS FACTORY OLDSMOBILE 15"x7" RALLY WHEELS

Would anyone know how deep of a trim ring i would need for the factory 15x7 rims?

If I remember correctly from my brothers 74 Cutlass the 2 7/8 deep ring which also is used on the 15 x 8 Corvette rally wheel fits.
Seems the design of the Olds wheel allowed for the deeper rings on the 15 x 7 wheel.
