I can't think of a reason they'd be knocked out other than cabin pressure. Same reason they added the door jamb reliefs with astro ventilation. My sedan doesn't have astro ventilation so there's no need to equalize pressure.
I'll thumb through the Fisher manual later. Certainly could have been missed by some line workers.

Rick,

If your original divider board was punched out, I’d leave it. I just checked my file photos and my 4A car was not punched out. Maybe Grady can chime I with what his car has. I’ve seen them both ways on Baltimore cars. I don’t recall off hand what my COPO has. Will find out later.

Nice job on saving the package tray insulation. I did that on one of my cars and was surprised at how easy it was. You have to have good insulation to start with though.

You are really cruising on this project!

Very nice.

Phil

Both Grady's blue COPO and 300 are punched. He messaged me earlier. I decided many years ago that I would not restore our cars per popular vote or majority rule but rather how we found them if we knew for sure they were unmolested. Doing anything else messes with the history of these cars.

67-69 Camaros have a rectangular holes in the same area of the divider. I heard it has something with air being able to escape when people sit down ..Joe

Phil, we are making good progress but working nights and weekends is getting old. I'm hoping we can wrap this thing up in a month or two. Still need a few parts and will post a wanted ad soon. I just realized tonight that I believe these hoods use a rear V shaped weatherstrip across its entire width. That will not be fun to locate and the repos are nothing close.

Nice low mileage steering wheel.

Thanks so much for all of the pictures. There is so much detail going into this that no body would ever get to see if you had not posted pictures.

Even though it was low mileage it was not in perfect shape and I still sent it off for restoration to make it perfect. Expensive but worth it.

That was one of my main reasons in doing so, to help others with their projects. I love the behind the scenes stuff on these cars and love detailing them to the 9's especially in areas that are somewhat hidden. I am weird like that.

Before some hammer on me, there is a reason why my wheels were painted black. I purchased a set of day 2 take off wheels and tires from a collector who bought them from Vince Emmy. These came off an original COPO early in life from what I was told. I cannot confirm that however. Usually I always see Dove grey on the backs of these while NOS wheels are commonly black. The fact that these were very low mileage take offs from a COPO was the reason why we restored them in black. In addition, the YH's I had off the Maroon 69 Z28 which was totally original and had survivor wheels were also back on the back so that is what I did. Pictured in the stack of tires/wheels off that Z28.
