How and why do 65 Barracudas have various trunk props?

Just wanted to show how my 65 Cuda trunk prop is. It has the locking mechanism on the left and right side of the car. I had someone send me a PM that they did not ever come with them on both sides of the car. I guess the factory did what ever back then.
I did take some pics back then and just forgot to post them and happen to come across the old pics today. Yea I'm a little slow...
You'll notice that the truck bracket is factory on both sides of the car and trunk lid.

That bracket mounted to the underside of the body is not for the ratcheting trunk prop!! The bracket should be mounted along the side under the trunk rail!!
