'67-68 Scott Drake Trap Door w/6x9 Speaker Pods

So I purchased this from Holley, of course no instructions or hardware of any kind came with it. The only thing I see pre-drilled on it is for the latch, and it's obvious that the factory bolts on my current trap door latch will not work here, it will need self tapping screws. As for the hinges, I can't tell if I need to remove the clip nuts off my old trap door and install them on the new one. There is a hole where it looks like you would clip then but then there is no exposed hole so the bolt can pass through, I'd have to drill one. If anyone on here has one, I'd sure like to know how you mounting it up.

Thanks in advance.
