Did you think maybe the pics weren't big enough?
Damn it these things are in tight. I wish I just left them alone now - I've made a real mess of it [
]
I sanded down the attachment pins on the inside of the hull so that they were flush with it and then tried to remove it. I removed one (with a lot of effort) by cutting it off but had to drill out the plastic from the holes. A real nightmare. If anyone else is thinking about doing this - don't.
