273 5 speed conversion to ax15??

Hey y’all,
I have been fighting the 904 in my 65 273 barracuda for a couple months now. She is good and blown up. At this point I’d like to 5 speed swap the car. I found an ax15 in a 96 Dakota. 360 bucks for the trans and all that goes with it. I do not want to lose the 273 because it is a stout little motor. From what I understand the 273 is internally balanced and all the magnum stuff is externally balanced.
What will I need to do to convert my car to a 5 speed?
Will it be possible for a 273 to work with ax15?
I’m on a college student budget. So am trying to keep it cheap.
Thank you!
