One of the more interesting convolutions of the English language: "Custom Fit" plug wires are built WAY TOO LONG, so they can be used on every engine Detroit ever built. "Universal" plug wires are cut to fit your particular engine and plug wire routing system. Go figure.
If you want to do this the least expensive way, go to a REAL parts store (not the exhaust tips 'n' blue headlight kind) and buy eight distributor terminals, a tube of silicone grease, and a plug wire crimper. Maybe $20. You can "probably" re-use your existing wires and boots. Dab of grease on the wire, slide the boot up a few inches to expose the metal distributor end. Cut the wires to length, crimp on the new end, slide the boot down.
I for one will NEVER use carbon core wires. My preference is the helical wound wires supplied by any number of companies. I tend to use MSD Super Conductors. These come with the plug end already on, and a crimping tool to do the distributor end. I've never had any luck with the MSD crimper supplied, so I use a pliers-type.
I tend to make plug wires about two inches longer than "perfect", so if I burn a plug end, I can cut it and re-crimp without having to replace the wire.
