727 in a 1966 dart wagon! HELP

I have another option, it's a 904 out of an 88 van. I'm sure it's a lockup converter. Can I use it without the lockup converter, By using a stall converter? What about the electronics? Can they be deleted or just not used?

Some of the front components are different for lockup/ non lockup. If the front shaft has a smooth area resembling a stick shift pilot it's lockup.
