I know a guy who ordered a 66 Impala from Penske Chevrolet. I forget is he said it was a 396 or 427, but it was also a 4 speed car and ordered it with the specific gears he wanted and a posi.

After taking delivery and having fun with it that weekend, he quickly realized the rear in the car was not what he specified. Took it back and had Roger himself look at the car. Story went Roger asked someone to bring him a floor jack and he spun it right there. No posi and wrong gears. He got the right ones dealer installed!

Don't know if the mistake was a factory one, or if the dealer didn't order the car right.
