If I remember correctly, the Clewett wires are bigger in diameter than the Beru wires. Thus, the original wire separators won't work. Go to your local Advance Autoparts or whatever and buy a couple of packs of wire separators as used by good ole American hotrodders. The ones I used are made to hold two wires and can be spaced to nicely control the plug wires. I think there were about 10 to a pack and I used most of two packs on my twin plug engine. Good luck!
