I made the B pillar cross bar first and then made my support bars, but because I have a slight angle of my support bars my cross bar didn't really match the angle of the vertical support bars mainly because I notched it at 90 degrees. I didn't notice it until it was all tacked up.

I ended up making a new cross bar but rolling it back about 8 degrees before notching it. The end result was a much better matching of the three bars.
