Trunk Prop Rod location

I have the spring loaded prop rod for the trunk on my 66 Barracuda, however, when looking to install it I find that there is no hole in the trunk lid for the upper end to go in. Can someone who has the prop rod on their car get a measurement where the hole should be for proper operation? The mounting place on the left rear fender inside is there and the hole bracket cover is all there just not one on the lid. I suspect that this car had been hit in the rear at some point and the lid was probably replaced with a lid for some other style.
