72 Supreme in Cameo White
A 51 bucket seats
RG 972 interior with matching green vinyl roof.
U code 455 auto.

Any idea as to how rare this combination would be?

Thanks,
Dave

 

Rare? Likely not rare may be a bit on the uncommon side. Ill bet a fair number were White Green Green.
A dash/dash where the color code should be is rare(er) as that indicates a special order color not available as an RPO color.
No way of breaking color or options down to a number (with exception of W29/W30s and U X code cars).

Here is info on the engine/trans options:
