Need some electrical help with my ‘68 Plymouth Valiant 100

And one more thing:

Back in the day, when you used to be able to go to pretty much any junk yard and leave as the sun was going down $30 poorer, with a wheelbarrow full of parts, questions about brake upgrades were fairly straightforward work vs reward.

Now that most of the junked A-bodies have been crushed, it's a much bigger, and more expensive deal to get the parts you need to upgrade or modify your brakes (or anything else), so answers that may have been right twenty or thirty, or forty years ago may no longer apply.

$20 or $30 or $50 and some skinned knuckles for somewhat better braking? Why not?
$1,000? Different story.
