E body center ac vent interchange

[Ohiowoodchuck]

The whole assembly is missing for my 74 Barracuda. I do have the plastic ductwork but it’s the vents that are missing. I see some are saying that 71-74 b bodies are the same. I found a couple of them but will they fit right in the factory spot. I see most of them mounted in a longer set up

The vent housings are different but the vents themselves are the same. Here are some pics of a center E-body assembly I repaired making one good housing out of 2 broken ones, and a b-body unit I used as a donor for new vents.

Thanks for clearing that up for me.
