How do I put the coin box back ?

OK I've tried to put the box back in, and I've come to the conclusion its time to "post-a-friend !
I understand the coin box (drivers side on dash) simply slots into the two pivot points but I also see a spring at the rear of the housing. Any idea how this spring hooks to the coin box....It needs the spring as the con box just falls open however cannot work out how to put the spring onto the coin box and somehow fit the box back into position all at the same time.

cheers
