Hey WTR,
Thanks! for the link
...very informative
The top diagram specifies for the Shoulder Strap mounts ta be mounted 0*-10* below the drivers shoulder
...& a diagram down lower, shows the SS mounts being 0* - 20* below the drivers shoulder
Sitting in the seat of my racer, the drivers shoulders are ~8' above the back of the seat
...& from the back of the seat to the rear of the racer is ~12"
Pic w/Shoulder Strap about where the drivers shoulders will be

When I lined up ~10* angle (as suggested in the diagram)
...going downward from the drivers shoulders, toward the rear of the racer
...that "line" went "way out" behind the racer

I'ma thinkin'
...we don't want to mount the SS mount all the way back, at the far edge (not strong/sturdy enough)
...& we don't want to mount it right behind the seat/driver (too steep of an angle)
So, I'ma thinkin' maybe it would be best ta "split the difference" (Soloman)
...& mount 'em ~6" behind the seat/driver
Also, I "harvested" some Center (manually adjustable) Seat Belts, out of a couple of old Isuzu NPR parts trucks that I had/scrapped recently
...so, for now, we gonna do some testin' with a set of custom DIY 3-point Seat Belts
* Yes, I realize they don't qualify for use in an actual EA race
...but, should be adequate for some "home track testing"
