if the hood closes to the correct position, there is no adjustment .... the highest, "hooked" arm should catch in 2 positions, the other smoother arm is part of what makes things move, it doesn't hook anything - the plate piece on your hood has 2 levels on it that hold the hook, one of them may be damaged or bent .... also make sure there are no washers holding the latch mechanism lower than it should be, like under the sheet metal header it comes up thru
