This is the arrangement shown on the Part Plates in the V8 parts book, but it is extremely rare to see as it was used only on V8 cars with TL and without power brakes.
Realistically this would only be 55 Super, and 56 Deluxe and Super, but nearly all of those cars had power brakes, and for the ones without, it's likely that TL would not have been equipped.
The production timelines are also tight, as any such cars would have had to have been made between 6/1/55 (optional on Super) and 5/1/56 (standard on all).
It's also theoretically possible to find this on 55-56 Customs, as it is known that some were built without TL, but it would be extremely remote as there's no chance that a dealership would spec a higher trim level without the cheap and popular power brake option, and likewise it's hard to imagine that anyone would order one custom like that, not to mention that only a couple % were built without TL in the first place.
