okay
first take out your lens 
then pull out the bottom part of the outrigger first ( pust it foreward then pull outward and it should pop put
then take out top part, it should come right out
to get the strap out put a knife or other rigid narrow object in the back of the out rigger then pry it gently to free the strap ends, now push it so it is perpindicular to its orignal position then push it out through the back
... i realize this isnt the most helpful walk through. some one deff needs to make a tutorial like the pole cutting one with pics, if i had more time i would
hope it helps a litte
