I don't know if it's true, but it wouldn not be a coporate impossiblity. The factory will do whatever it takes to get the car out of the plant, and if you saw some of the conditions of the cars before new-car make-ready, you'd understand this "gotta' get it off the line--RIGHT NOW!"
(The one of the many issues I have seen with pre new-car make-ready was an issue that I just could not understand the menatlity: Whether it was an issue of the windsheild urethane machiene or whatever the reason, someone at the factory used the headlinder as a rag to wipe urethane off their fingers. My best guess is that they intentionally dug into a glob of wet urethane to remove it; then, they wiped it on the headliner.)
At the factory, the car has to go because it's huge machiene, wherby one glitch creates a domino affect, and such ripples can cost millions of dollars. The car had worn out its allotted time, the worker didn't have a rag to wipe his/her hands, so the supverisor says, "Wipe it on the headliner and move on."
If they had a Firebird chassis and didn't have Firbird front end metal, they would hang Camaro metal on the car if they had Camaro metal. What are they supposed to do with this chassis without a front end? They have storage issues too!
This is interesting and it might shed light on what I thought was hogwash from long ago. I have had a strong interest in f/g/f cars since they rolled off the line. In the very-early-to-mid 70's, I remember seeing 9's wearing Camaro front ends. Some were wearing the RS and/or SS hide away headlights. These guys swore that these were specail cars.
You see, Firebirds haven't always been cool, so these guys were saying that they were specail Camaros because they were bow-tied all over. I don't remember if they deleted the side birds, but the @$$ pan didn't say PONTIAC on them. I never got to see inside of the car or look under the hood. Heck, I was a preteen/young teen, and they didn't want little kids near their cars. Can't blame them; I don't want little kids around my vehicles either.
As I grew older and started driving and started building signifigant wrenching skills, I figured that these Fiebirds were wearing sister front clips--heck! they bolt on with about a half dozen bolts--because Firebird clips were already scarace in the mid 70's.
Maybe there is something behind the story because I remember seeing quite a few "specail" 9 Camaros.
