Hinge Question

At the last show i was at I started to shut my hood and when I pulled down on it I heard an extremely loud BAM like a gun going off .......afterwards my hood on drivers side will not shut flush with fender .......I have removed the splash panel to look at hinge and watched hood go up and down and I don't see anything wrong, well broken anyway. What am I missing,:banghead: the hinge is a little worn out it kinda slides along fender when opening and closing, but still moves freely. It is a little hard to pull down right at first if it is fully open after that its easy. Does anyone make new hinge assembly, complete with springs ? John
