PLEASE HELP! '64 emblems on '65 GT!

My brother recently bought this '65 GT convertible that we are going to restore and show along side my '65 GT that i had a recent 273 conversion thread on. Both cars are ss1 (french ivory). The convertible is a california car (LA plant). We assumed when we bought the car the V8 emblems were added at some point off a '63 or '64, but the car retains it's original sheetmetal despite a respray many years ago. So i began to search the internet and shockingly came up with a bunch of '65 darts (9 so far) with the v8 emblem. A couple of the cars had articles or names attached to the pictures linking them to California, Arizona, Washington, and Hawaii. Does anyone have any clue what the story is here? We are going to be getting the car repainted and want to be 100% certain these emblems belong, but we are puzzled by the whole thing. Here are all the pics i've found (my brother's car is first). Dying for some info....PLEASE HELP!
