slant bellhousings

Hey all, forgive me if this has been asked before. I poked around a little and didn't find a definitive answer.
I have a 67 barracuda with a slant six three on the tree. I want to put a a833 four speed in it shifted on the floor(obviously).
The three speed bell housing is original to the car(67) and the a833 is a 67 or 68 a-body unit. The three speed is still in the car so I am not sure if it has the dual bolt pattern.
Does anyone know if the three speed bell will bolt up to the a833 without taking it apart to look?
Thanks in advance guys. I always appreciate the knowledge I get from here.
