This is one of few times I'll say this...

Go to a mechanic or the dealer. Get the right length of non-resistor 8mm ignition wire. They can use your existing connectors (they're typically "Screw on" where you just unscrew the connector from the old wire, and screw it on the new one). If the mechanic is friendly he might do it for free (I have it happen all the time and give the guy $5 or $10 for his time).
