    This looks like it would be a perfect solutio0n for rear seat shoulder harness installation, looped over the streamlined tube and use a standard web retaining clip to secure.
    Cheap at ~$80 per seat (Qty 2 sets required):

    Not cheap and would require Qty 4, :

    Aha, auto/racing supply would be much less expensive and perfectly adequate

    This of course assumes the streamline tube is in fact higher than your average rear seat passenger's shoulders.

    Thank you so much!. I first need to find out what the streamline tube is in the first place... then I can see if it is generally higher than my pax' shoulders.

    It is the tube that the seat hangs from.

    Right... sorry I am a Tri Pacer newby owner.
    Is it a requirement for the tube to be above the pax' shoulders? If the harness slopes slightly up and then over the pax's shoulders down to the buckle is not allowed?

    The angles are better to keep from compressing the occupant's spine. I believe most anyones shoulders will be below the tube in a Tri-Pacer. Read AC 43.13-2B Chapter 9 to educate yourself on shoulder harness.

    Damo, you might look at the previous posts that I merged your thread with.

    If I could figure out how to remove my previous posts (8/19/20), I wouldn't confuse myself!
    Immediately behind the rear bulkhead of the hatrack is definitely a streamline section crosspiece! I welded brackets to that, but it would be feasible to wrap a bracket around the streamline to achieve a similar result. Cables run forward to the Y harness fittings.
    The first photo shows a cable coming forward through the bulkhead to the Y harness. The second is looking up from the 'hell hole' opening to show the bracket wrapped around the streamline and welded. The brackets are at 18" centres which corresponds with the centreline of each back seat, and the cables are horizontal from the bracket to the passenger's shoulders, which should be acceptable for spinal compression considerations.

    That was posts #8, #19 and #20 above.
    I tried to, but couldn't do it for some reason--competence might have something to do with it!!
