After thinking about my hood latch failure I realized it would be a lot safer to have the locking nut mounted on the top side of the upper hood latch bracket. I purchased my car as a roller with the body work done and the latch was installed with the locking nut below the upper mounting plate tightened against the tack welded latch nut. It made it 22K miles like this and I'm not sure which way its done from the factory but the way I've done it below is much safer.
Pic is with the latch off the car but I can still just barely get a 3/4" wrench on the nut with it installed on the hood for fine tuning the hood latch height.
