Topic: plastic wire loom source

[bluemax]

I am working on various details in the engine bay of my '86 SVO and need a source for 3/8" open wire loom or convoluted tubing. This is the size used on the relay to starter cable.

The tubing at Home Depot is different in color (more grayish than black) and the tubing itself is formed differently than the oem. Will anybody notice, perhaps not, but I would like to try to remain as close to original as possible.

What have some of you been using?
