The 64 Polara lights pictured above are different than the 64-5 lights in a Fury-Belvedere-Coronet. I don't have a pic but the same lights can be found in a 68 New Yorker 2 DR H/T.
If you need everything the C body light housings typically don't rust since they're mounted to a plastic sail panel.
Several vendors sell the plastic len's but I haven't seen any of the aluminum outer rings or light housings repopped...
Correction I googled it and these are shown as C body lights at 521 Restorations...
