Seatbelt Harness

[writah@juno.com (Alan E Gressler)]

It's been about a hundred years since I've installed a set, but as I
recall, one caution on installing the shoulder harness is to ensure that
the mounting point(s) are not too low below the driver's shoulder
(something like the rear-portion of the harness making no more than an
angle of around 20 degrees with the horizontal... i.e. don't bolt it  on
the floor.)  The risk is supposedly a compression fracture of the spinal
column if you're in an accident. 

 Anybody know for sure?
