Doug's headers not fitting - frustration

I took my lunch break in the garage to loosen up the bracket bolts and take a few photos. After loosening the bolts I lifted it up and sat it down carefully and it went right back to the same spot. The one photo I wanted to show the coupler hitting didn't turn out for some reason. Cheap phone I guess.

It looks like there's something weird going on with this one, but if anything that should raise the back because if anything it's tipped to the front.

Sing out if you see anything questionable there.
That doesn't look right to me. The actual brackets just don't seem right. Also, the brackets hanging that far off the biscuit, and the nut so close to the wall.. just seems different to me for some reason
