Was this a Hurst rent a car?

Do you have a broadcast or build sheet that backs this up being a Hertz rent a car?
I had a '71 Duster 318 column auto with an 8 3/4'' 2:76 open ratio rear end in it.
It was an Avis rent a car, and on the bottom of the broadcast sheet it said Avis Sales in typed comments.
Nothing on the fender tag indicated that it was anything but a '71 318 column auto '71 Duster.
But, on the broadcast sheet, it was Y4 (sold car) and the Avis Sales remark at the bottom.
I'm sure it came with the 8 3/4'' rear end because it was a rent a car.
It was Lemon Twist with a black interior.
Most rent a cars are conservative packages with a bit of insight to how they are being used.......which is hard at times.
So, it makes sense that the '71 Duster 318 auto had an 8 3/4'' rear end in it.
It makes sense.
