I am planning to install inertial reel shoulder harnesses harness for the front seats of my LIV (under construction). I have seen the archived posts on the topic but am still not clear as to how (and where) to create acceptable anchor points for the upper (shoulder) harness in a non-pressurized IV. If anyone could point me in the right direction it would be greatly appreciated. Also I am also looking for recommendations  for a manufacturer. Thanks.
