Od833 4speed in 64 valiant

It's an O'D bell housing with the bigger bearing retainer. It's behind a 318. I'm basically mocking everything up and collecting parts right now. All I have is a 76 cast iron O'D Trans, 360, and clutch pedal assembly. My neighbor has a 80s dodge pickup with the bell housing in it. I didn't want to go through all the work removing it if it's not going to work
Is the overdrive transmission a body or truck transmission I'm confused. The 318 and 360 both have the same bellhouse pattern and if it's a light duty truck it should be 10 and a half inch clutch not 11 but you'll have to make sure. Pictures of what you have would be helpful.
