Id put a bigger gusset on that rear bumper if i were you. If you ever happen to need to get winched (like being stuck on soup bowl lodged behind that big rock on the driver side) then it will bend the crap out of those mounting plates.
If you mean the flat bar, those were only there to align the bumper to the mounting plates. I have some gussets I was going to use, but it got the flopp it treatment. I'll look tomorrow and see if I can get at them.
