Are 1964, 1965, and 1966 barracuda and 2 door valiant doors the same and interchangeable?

The 1966 key hole is much bigger, as I recall, which continued until ~1969. The 1963-65 keyhole is the same, but I found the 1963 lock doesn't work with a 1965 key since the slots on the keys differ. A guy near me in El Dorado Hills, CA parts out many early-A's. I recall he has a 1963 door currently on the Sacramento Craigslist. He ships. Most sheet metal out here is fairly rust-free and cleans up nice.
