That is interesting and proves that not much modification was required to create a "new" 1954 Kaiser. I always wondered about that. The 1951 Packard supposedly was just warmed over through 1954 and some felt through 1956. But with Packards there were visual cues in the sides more than in the grilles - to denote a model year change.
Such as Scallops or more stainless. But with Kaisers, the sides did not demonstrably change from 1951-54, the details changed as we know were the taillamp area and the grilles.
