What would be the best way to mount down my box in a trunk? L brackets? Anything else that works better? I prefer not to drill any holes threw my trunk if i dont have to. Would jamming extra stuff against the side of the box work as good if its tight enough? My only problem with the L brackets is that the screws dont stay tight after time because the trunk metal isnt really thick, its like sheet metal.. Should i use rivets in the frame and screws in the box maybe?
You can do like I did. Just make the box so big it barely fits in the trunk. Mine is wedged against the trunk metal itself. It won't even come out of the car I don't think. I had to take parts of the car off to get it to fit.
