If your talking about the shrink tubing that runs form just inside the headlight bucket back you'll need 3/4 inch shrink tubing. This will allow you to feed the bullet connectors through the tubing. It shrinks about 50% when heated. I've done four CT90's this way and it looks nice. The tubing I had was white so I gave it a shot of  Duplicolor FB-108 silver paint to make it match the original color.
