They should carry the Taylor brand for 10mm wires What I did is go to NAPA and order their seperators (same as the others) and drill them out to fit the wires. They look awesome and red to boot! I may have a picture.
The NAPA seperators have the screw in the center and I got both packs for like $15.00. They had different colors but I got red to match the wires. Let me see if I can dig up the picture. Back in a few.
I'm a cheapskate. I just use black zip ties and form a loom for the wires. Crude but effective, and doesn't look too bad in my opinion. I'll be posting some pics of my car later on tonight, so you can be the judge if it looks ok or like azz.
