Post pics of the problem

You can see how the angle of the bar coming in is off from the "post" off the A pillar. If I were to let the bar sit "naturally," it would be above the post it joins to. The angle is bad enough that I can't get the coupling to move into place and bolt it down. The lower bar on this side (and both on the other side) went in without any trouble.

Sorry that the photo is upside down. Stupid iPhone is having trouble figure out which way is up.

This is why I internally sleeved the cage and it took me having to keep the entire cage loose until I pushed it all together...it took hours to use rubber mallets to make it all come together.

Plus someone added a door bar to your cage which makes it even harder to get back together...
