    31779 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from You cannot go wrong Worked great. Factory style boots for the HEI distributor. But HEAVY. And you can use the locking cap. On the spark plugs the boot goes over the whole plug perfect. They are cut to proper length's so you don't have to cut and put ends on. They are not sloppy extra long. They are RED and add some color to your engine compartment, and goes great with that red distributor cap. They perform better than most high end wires and are quiet. (no radio noise, important to me with ham radios in the truck) . They make factory wires look dumb. And, they come with a set of wire labels and a tool to put them on, nifty. Also show off stickers.
