A230 3 speed

I have a 3 speed standard trans and bell housing in a 67 Belvedere. I don’t know anything about how to tell what transmission it is though or what works where. It is from a /6 so the bellhousing won’t work for you. I did start the car and run it in the air before I started parting it out. Located in San Antonio TX. PM me if you think you can use it.
