New Member/"New" Truck

If it runs and you like it, dont complicate your newbie status with converting it to 12 volts. It's not that hard to switch back to positive ground either.

New wiring is available from a number of re-production vendors. (even with an alternator)
Brakes parts are also available and would be a great place to start (after the re-wire).

Heaters -- are they needed where you live? Probably not, so one more thing not to worry about.

Fix what you can, ask for help for what you can't and enjoy a great old Ford pickup.
