69 dart 340 drag car... back to street car

I am resurrecting an old drag car. It is an original 340 automatic. Has full tubs, narrowed 8 3/4, and frame connectors. It has an old dual point distributor that I am replacing with a Mopar electronic ignition. Currently installing a Painless wiring kit, which is anything but Painless, wont do that again.

I do not know the correct locations for a few things. Ballast resistor, ignition coil, and where to mount the ignition box. I know it is not going to ever be factory correct, but I would still like to have things close to where they should be. Any help appreciated.
