I looked at all the pictures and most the bars look pretty good but (and I am not an engineer) I would have thought that a straight bar between teh "b" pillars would be a good idea to firstly shorten teh distance of teh harness and thereby reducing teh possibility of stretch in teh harness as well as stopping teh seat/s from going out through the back of teh car if in the event of an accident tehy became loose dislodged or broke free of the mounts.

My humble two cents worth.
