Junkyard Electronic Ignition

Tomorrow I'm pulling a Super Six out of a 79 Volare in a junk yard. It was suggested that i also pull the distributor if I want to put electronic ignition on my /6.
Question: will I need to pull everything including the housing and bearing which the vacuum control attaches to or just the cap, guts and shaft. Also, should I be pulling any other components for the ignition?

Thanks
