Add in a 12V+ bus bar and new red cables to alternator, battery, starter and bulkhead connector and you have a nice clean engine bay. Of course a new modern coil will let you remove the ballast resistors, putting a toggle switch on the engine bay light eliminates the one on the firewall and the whole start relay thingy can go too with new red wires just described..... clean.
