suicide rears on my integra

ok first off i realize this isnt a mini truck question but i figured i could find some help on this topic in here.....

I want to get started on some suicide rear doors on my integra.. Yet im bein told by alot of people that i really shouldnt do it because they will sag, the metal is too weak (which is true on a integra) and that the dog leg poses a problem. So i was wondering if anybody could explain a way for me to do this or post pics...anything would help. Ive seen it done before so i know its deffinatly do-able im just looking for the "correct way"

thanks btw I will be fabricating my own hinges so just buying a kit is not an option
