When I did the rear roof rails on my 67 I used the panel bonding adhesive.It worked real well,still holding up after 4 years. The previous owner shaved them and mudded them up.Talk about lots of rust.Had to fab the channels for the roof.

Re: 72 Concours wagon project

George what kind of set up time does it have? I heard you it needs to be positioned quickly.

Re: 72 Concours wagon project

Fabricated the shift linkage today. The pivot needed to be moved back 3" to align with the transmission selector shaft. I cut and extended the frame bracket and used a longer cross shaft from an X body. Also used the down rod from an X body and extended it 2". With the factory column shifter it will go into all gears, including first.

It tucks up tight to the floor, plenty of room for the exhaust.

Re: 72 Concours wagon project

The tool well showed up last week, nice piece, quick shipping as well.







I'm assuming the step in it is to allow for an overlap weld rather than a butt weld.
I think I'll use Pete's suggestion and make it a few inches deeper than stock.

Re: 72 Concours wagon project

Decided on the placement of the PCM. Fits well and easy to access if necessary.
The wires will be run between the fender and inner fender, under the brake booster and behind the engine. Some will need to be extended but this seems like the best place to put it. The few that need to go inside the car will enter through the speedometer hole, will not be using the speedometer cable and the hole and grommet are sized perfectly.







This idea was scrapped, the wires were not long enough to reach and decided to use a different PCM

Re: 72 Concours wagon project

Hi Philip,

Agree with making the well deeper, but remember then that becomes the lowest point on the rear of the car.

My original load well was horribly scarred up from being backed over things, and it was tucked up in a position the same as an El Camino fuel tank. I would be worried that lower would attract all sorts of interesting carnage.

Everything else looks like it's going well for you.

Re: 72 Concours wagon project

Good point. Mine was all beat up and the bumper has scrapes along the lower edges too. And then there are the dents in the right rear quarter, left front fender, drivers door, tailgate and hood. It appears that at some point the left rear tire fell off, folded up the back of the wheel opening, bent the lower control arm, wore the backing plate off flat on the bottom probably from dragging the pavement and then it appears the wheel and tire tore up the storage well on the left side. IMO the previous owner didn't know how to drive well

Re: 72 Concours wagon project

Yours musta been owned by the same guy (or relatives of) that owned mine. Every portion of the body (doors, quarters, gate) has been shown some love. That doesn't include the fact that the car had a new front clip and (I would find) needed a new frame. Real on-road demo derby driver I guess.

I keep telling myself that at least mine didn't have rust in the floors or roof/front window area. Load well, rear quarters, rear side windows... something else entirely.

At least my little girl loves riding in it.

Re: 72 Concours wagon project

More progress, removed the front springs to use in the frame upgrade. The wagon springs are shorter and stiffer than the ones in the El Camino. Looking at the rear springs they appear to be the same height but the wagon has a wire diameter that is twice that of the El Camino. Thought I took a photo but can not find it

Cleaned and painted a bunch of small parts today. About 3 hours to make them look new again. gotta love Arizona metal, no pitting of the steel after 40 years of use.



These are the rear frame braces, first ones I have seen in person. They are made of a lot heavier steel than I thought.





These are the original park brake cable guides, they are rubber coated where the cable rides.



Like the El Camino the wagon has raised axle bumpers. The bracket also moves them outboard. From the condition of the rubber they have been in contact with the frame.

Re: 72 Concours wagon project

Hey Philip,

in your first picture, center, what are the 2 "C" shaped pieces with the holes in the ends of the "C"? They look familiar, but I can't remember what they are for/from, and my El Camino and Wagon don't have them.

And isn't non rusty stuff fun to clean, and aren't clean painted parts fun to reassemble?

Those are the standard brake line retainers used on the rear brake lines of chevelles without factory airshocks. El Caminos and other Chevelles with factory airshocks used the version that included stone guards to protect the air shock bladders. Those are in Phillips photo, also.

Re: 72 Concours wagon project

Interesting. Never have seen those on a car, either running or a carcass. I have worked on several original 70-72 Chevy A-body cars without those. All had clips on the axle tubes.

Were those a year or plant related item? Most of the cars I have owned/worked with were Van Nuys builds.

Thx
Tom

Re: 72 Concours wagon project

The small c shaped ones are off of a 64 - 67 El Camino, seem to be for protecting the brake lines. The 68 - 72 version covers the brake lines and the lower arm bushing, still don't see how it protects the shock. All the El Caminos I have seen had one type or the other depending on the year.

Re: 72 Concours wagon project

Found the photo of the springs, it was hiding in my phone.

Shorter ones are out of the wagon, the other from the El Camino, both had small blocks with AC.

Re: 72 Concours wagon project

Recently ran across this document at the GM Heritage site,



It states the Concours wagon had the area between the tail lights and the trim blacked out. Mine has been repainted so I can not tell. Has anyone seen a Concours with original paint with that area painted black?


And this page that shows both amber and clear parking lens used depending on model.



It was found here
