No difference in the plug wires between points and electronic ignition. The distributor cap connection changed when everyone went High Energy, so you'll want to get wires that match your cap's method of wire attachment.
I'd ask Rick (Sunroof GTX) if he could scare up a set of Firecores in black for you.
He's a board member and the product is solid, fairly priced, and he gets the lengths right.
Ignition wires, even the carbon saturated filament wires that used to be stock back in the day, will work just fine for 5K miles or one Summer's worth of driving. Even though advertisements hype everything under the sun, there is really very little or no power to be gained by using great wires, until the original wires start breaking down. It hurts me to say this, because I really like technology, but it's true.
The voltage the ignition system makes is by definition the voltage it takes to get the spark to jump to ground. Doesn't matter if the system is capable of 65,000 volts; if the spark jumps at 23,000, that's what the system delivers.
Problems start happening when the plug wants, say, 30Kv but the insulation on the wires breaks down at 25Kv. Now the spark plug doesn't work, the power goes through the insulation of the wire, to ground. Another thing that could happen is the plug insulator is carbon fouled, or there is a carbon track to ground in the distributor cap. Now when the ignition coil discharges, it has current flow at a very low voltage and there's no spark.
The wider the spark gap or the higher the compression, the more voltage it takes to get a spark to jump the gap.
Also back in the day no wires were any larger than 7mm.
Now on to bogus resistance claims...BOGUS! The way the spark energy travels though the ignition wire has NOTHING to do with DC resistance, which is what an ohmmeter reads. Think about it...the distributor rotor doesn't actually touch the distributor cap terminal, there is an infinite resistance (open circuit) between cap and rotor. Yet ignition happens. High voltage electricity has its own set of rules. That's why electricians working on high voltage power lines have to be specially trained.
Finally you can use a timing light with a clamp-on sensor to see if any plug wire is firing. If the plug is fouled or there is carbon tracking there won't be enough of an event to make the timing light flash.
