No idea. I made mine, the key to making good crimps are take your time and a good vise to hold the crimping die. Once you get the hang of making the crimp its easy. Nothing will look better than a custom set of wires. I went through 3 sets before I got the look I liked..lol
Mine are straight plug and held in place with an anodized aluminum wire loom. don't get the cheap tin looms . They will never look good. to me they all seem to have that cheap tin universal fit look. I bought mine from summit racing, they are for the Pontiac V8 and look great!
