What 4spd trans do I have? Is someone looking for it?

I recently purchased a project car 74 360 4spd. It came with a trans but from what I have researched it is not numbers matching to my car. Here are the numbers OB346728
PP833 3132 0162

It's 23 spline but has a 4.80 imput bearing retainer. It didn't come with a bellhousing what one will I need? If this matches someones car by all means let me know. I'm not married to it.

Post a picture to determine what it fits. That's a 1970 trans from Hamtramk...

It is from a 1970 Challenger.

Here is a picture
