3-Speed Shifter Identification

I cleaned it a little and didn't see any numbers, but I probably didn't clean the right spots. It came with a 64 Barracuda I bought years ago, but sold shortly after buying. It's a 3-speed shifter, but I've never owned a 3-speed before, other than a column shift, so I have no idea how to identify what it's for. I'm guessing A-body, but please take a look and tell me what you think it fits. Thank you in advance.
