Good comments. I'm also interested in knowledgeable comments and or
documented rules (as opposed to unsupported opinions) on the shoulder harness
installation. My older SCCA GCR indicates that the shoulder harness ideally
should pass over the shoulders at a 90 deg angle to the spine, but the
allowance is that it must in no case be below a line sloped downward to the
rear more than 40 deg (45 in a laydown position car). This is because the
shoulder harness should prevent forward motion and should not compress the
spine in case of rollover.
Is this a correct understanding of the principles involved? If so, I see
numerous cars with improperly installed shoulder harnesses.

Like I said, "Life isn't long enough for me to do another ground-up
restoration". Well, thank goodness, it is.
