I am not sure what this is called;

This is the only referance I could find for it;
circled in orange, and highlighted in red;
This image shows the truck release wire getting routed into it.
It's attached to the inside of the firewall, at the top, behind the dash vent ducting with four or five hex head screws.
I am guessing it was there to route wires up and behind the dash over to the drivers side for routing to the trunk along the drivers side of the car.


I am just wondering if it is reproduced.

Mine was broken into about four pieces;
I could leave it off, but the OCD part of me want's to reinstall it.

here's a picture of the big chunck of it

I am not aware of that plastic part available as a new reproduction however GM used that (or something very similar to that) on many GM cars. In the 1970s and early to mid 1980s. Across the cowl on cars that had power windows and/or power door locks. That wiring was installed by Fisher body and the plastic trough helps keep that wire neat as the body moves thru the assembly stages. Since it will never be seen I would go to any junkyard & find a decent 1980s GM G body car such as a Monte Carlo, Pontiac Grand Prix, Olds Cutlass Supreme or a Buick Regal. Find a car with power windows & power door locks. You will have to remove the entire dash pad to get to that plastic piece and take it out with out breaking it.

ok.

Thank you very much for speaking up

Use the core support push-in clips in place of the screw holes and drape the wires through them.

There's a couple diff types, but you could also use split tubing along with that, would look slick and near OE.

You could use the AAW under carpet wire channel, cut a couple slits, and straighten the small 'tab' with a heat gun. Do that along the length at the points the screws go.

Just some ideas.
