So it was a pain, but after a couple of hours on back inside the car I was able to pop both the latches, fold down the divider, remove the 2 bolts from the latch and pop the trunk open.
I was happy to see everything in good shape including the rubber floor mat, hardboard piece over the spare (which is one of the bald original wide oval red streak tires!) and that the jack, jack base, tire iron and storing spring were all there in amongst the mouse droppings
There is zero rust and the paint is in good shape so after a thorough clean the trunk will be great.
Here’s evidence of a factory 2 latch divider from the factory.
