How to remove "self-triggering" trunk lid prop-'65 Barracuda?

I don't see any hinge "covers" anywhhere. It's not the hinges I am worried about, it's the tricky hinge prop on the passenger side. Looks like it has upper and lower pins. I don't know if I should begin tearing it off by way of the pins, or if it separates in the center/middle somehow where the lower and upper pieces are sliding together.
