Anyone know how to get the plastic sleeve protector that goes over the rear wiring harness that goes in the trunk either new, reproduced, or used? Everything I find is either woven plastic, woven cloth, or coragated plastic. The original is smooth split plastic. Doing a restoration and my old one is cracked, brittle, and generally in very poor shape. Thanks Mike

I recalled a discussion several years ago about that, searched a bit, and found it. Unfortunately, it ended then without a source for the tubing. Maybe now, nine years later, someone will know.
Trunk Wiring Harness "tubing" availability?

I replaced the front to rear harness in my ‘68 with a harness from American Autowire. Replacement harness was an exact replica of the factory harness. Might try calling AAW about the sleeve.
I may still have the old harness. Will dig through the leftovers and confirm. Perhaps tube is still usable.

I may have that too. Let me know if you still need it and I will look for it.

Yes....still looking. Sent PM. Thx
