Are these louvre vents replaceable? 71-74 B Body

Are the 71-74 B Body dash louvre vents replaceable? The individual vents themselves, not the entire assembly.

They were made separately and assemblied so they can be disassembled, don't know if they make replacements or if you have to scavenge used one, but everything can be replaced/repaired/rebuilt. JUst take your time and be very careful. Sometimes when I can't figure out how something comes apart, I get a total junk one and then dismantle it however I have to, to understand how it fits together.
