For parts hunting reference here's the measuremants:
early type inner diameter is 168mm
later type inner diameter is 187mm
early type "overhang" is 45mm
later type "overhang" is 30mm
I think they can be swapped back and forth, providing the "eyebrow" around the light is removed for the late style grill install.
These are both metal grilles - not to be confused with the 74 and later plastic type.
Hope this helps!
