Annoying rattle/creaking behind driver side door

[fastricky]

Hello all, I wonder if anyone can provide some insight or guidance. My 2000 Boxster has a rattle / creaking in between the driver side door and the air intake. It occurs at any speed over bumps etc. I imagine this would have something to do with the convertible top mechanics? I should note I don't know the condition of my bushings, it's possible they are on their way out, would that be a factor in creating this noise?

On another note, the top while in good shape has a scratched and hazy plastic window. Would replacing the top perhaps also cure this rattle when the new top would be installed?

Any thoughts welcome and thanks in advance!
