Harness shoulder strap fixing for HANS use
Discussion
As highlighted in the October 2015 issue of the MSA Newsletter, its important to have your harness shoulder straps fixed so that they lie between horizontal and 20 degrees below horizontal for optimal safety.

Just wondering if anyone has already had to address this by fitting a harness bar to their roll cage and if so, did they just have it welded in or go for a bolt on solution?

Note, 0-20 degrees below horizontal is the recommendation, but they can be 0-45 degrees below the horizontal and still be legal.https://www.msauk.org/assets/msanews661015.pdf

Noting that shoulder straps should be crossed if they are a long way back from the seat yet people still seem to think it is correct for the belts to go straight back parallel.
On the angle question I did try at first with my shoulder belts routed to the rear seat belt mountings at an angle of about 40 degrees, the HANS yokes didn't sit flush on my chest and the top of the thing pushed hard and painfully into my shoulders when tightened. Routing back onto the cage at a gentle angle of about 10 degrees resulted in a much more comfortable HANS with the yokes pulled evenly into my chest. I am not sure the thing will work properly unless the yokes sit nice and flush on the chest.
