Switches, connectors, control units in 72 A body

Ok so im new at this and building my first car. http://www.forabodiesonly.com/mopar/showthread.php?t=111522.

Now my question is im fairly new to these cars. Been working on my for about 3 years but the only one I have worked on. Looking for a list of switches, connectors, regulators I will need for the electrical system. I do realize this is a odd question but would like to buy new ones. I do have a wiring diagram. Also going with MSD ign, and Mallory Dist. No AC or heat. Failed to mention I have a 72 harness stock and also a 12 circuit aftermarket harness. Haven t decided which to use.
