Just a thought....
If you're pertronix ignition fails you have to either have another unit spare in the car or a complete set of points, condenser and coil as you cannot use standard points on a pertronix coil.
A good middle ground is stock coil, stock points and a velleman electronic ignition kit.
The kit uses your points as a switch rather than a load bearing device, so they will never pit and should last for years without the need for replacement. Oh and should the velleman kit fail all you need in your glovebox is a condenser.

Any fool can make things bigger, more complex, and more violent. It takes a touch of genius - and a lot of courage - to move in the opposite direction.
