Lockup 904 question

This is what I am trying to determine. That would be simple, or are there differences in the case or other parts? Governor, maybe?
You already have the wire, correct? 904 is a 904. Mopar was good at adapting. They didnt change the basics. Cant know for sure. Threw my 2cents out there. I really dont know. Get to hotrodding on it an tell us.
