How and why do 65 Barracudas have various trunk props?

No, you guys are correct, I was looking at those pics wrong, and thought that was the upper corner of the trunk lip in front!! Now that I see that is a side view I can see that it is in the right place, and the drivers side looks to be factory! I can't tell from the pics whether they are side specific, but it's darned odd to see a drivers side mount!!
