Wire Harness Sleeve, where to get? Options

[bbrock]

I'm refurbishing my main wire harness and looking for suggestions for sourcing sleeve material to replace my brittle and oversprayed stuff. I know I can get PVC sleeve from McMaster-Carr as described in this old thread. But this doesn't quite get me there.

There are two sections of sleeve before and after where the two headlight circuits branch that are slit and taped sleeves. I'm thinking just buy some oversized PVC sleeve for that and slit it myself unless someone has a better idea.

On the rest, the small diameter sleeve appears to be heat shrink and maybe all of it is. Regardless, you can't get a tight factory fit with plain PVC sleeve without removing all, or most, of the terminals. I'd like to avoid that. So wondering what heat shrink material would have the same glossy black finish as the original sleeves.

Thanks for any advice. (IMG:style_emoticons/default/popcorn[1].gif)
