As @SoilSampleDave said it is a bit of a procedure to get the parts to align. Send a message to support at aurora-rally dot com and Costas will be able to assist with photos and videos if need be. There are so many adjustments on the tower that it's tough to say from the pics. The general idea, as it is reported in the video is to leave the bolts on the tower loose then see the positions and then tighten. A couple of millimeters difference in the head will make a big difference at the end of the tower. D.
