New Dragon Wagon Assembly

I purchased a 54x30 dragon wagon with workstation kit. I used the spacers to mount the catch tray so it clears the corner weld on the leg, though I am one spacer short? I’m also wondering if using the same bolts is recommended since the spacer limits the number of threads that catch, should there be a longer bolt in my kit? Is there a way to share photos, I’m hoping I got it together correctly? I found a few 1 minute videos on assembly, that’s about it?
