Review on X Alter Truck Extender Toyota Tacoma by Brandon Battaglia

Step 10 speaks of disassembly with a Phillips screwdriver, but has already been disassembled. I need the missing screws for the correct assembly. The holes in the vertical bars in the picture are the ones that came apart without the screws. I need screws to attach the bars. I had 12 screws (Phillips self tapping screws) that came with 2 brackets to attach the bed extender to the truck so I'm using some of these to hold the bars together until I can get more screws.
