The safety conscious side of my brain says " It would be nice to have a modern Airbag System with Head,Side Impact Knee and Rear Airbags " 

As we know In 1971 the Shoulder and Lap Belts were all that you got.

As an Ex-Road Racer it hit me like a cold slap in the face that the current Scroth 4 Point Belt Installation was incorrect and Dangerous.( The two Shoulder Belts were stitched together and buckled via push button to a single seat belt behind the seat back then looped over the bar and bolted to the floor. ( Seriously )

This past Weekend the New 6 Point MoMo Belt System was set up correctly.The lower " Anti- Submarine "or "Crotch" belts do more than prevent you from sliding under the Lap and Shoulder Belts.They keep the other 4 belts in the Correct Safety Position during an impact.

Now I can focus on Setting up the Fire Extinguisher.IMG_20190520_171355MoMo Belts1

In lieu of a Race Car Roll Cage or Roll Bar the shoulder belts attach to a Seat Belt Bar sold in the Pantera Aftermarket.

Note in the FIA Instructions that the angle of attachment in relationship to the seat and occupant is important.Too severe an angle (as the Schroth Belts were installed by a PO ) puts downward pressure on the shoulders and spine of the  occupant in an impact adding to injuries.

The Buckle and Loop arrangement will attach to belt Clips or Bars.

Also seat belts have a expiration date similar to a Snell Crash Rating in a Helmet.MoMo Belts3MoMo Belts4

Ok, I see. Wrapped around the harness bar. 

But what is the difference between the original setup and the new one? Crotch belts, obviously. But about the shoulder belts? They are now wrapped to the same bar than they first went over, so the belt angle from shoulder line to first hard point is the same, isn'it?

So what makes the first one dangerous and the second one acceptable?

I have to ask, because I don't have a clue... 😎

Looks great! Certainly the new and fresh belts will be safer than the old weathered ones. Sunlight really degrades the materials quickly. Sorry to rain on your parade but I had always heard it's unsafe to use harnesses in a non-caged vehicle, reason being that in the event of a roof cave in the occupant would be pinned in position and take the full brunt of forces which caved in the roof, versus a traditional seatbelt where the occupant could slump to the side- perhaps getting a bump on the head but avoiding a crushed skull or broken neck. I'm no expert just passing along a concern I have heard from others.

But doesn't the harness bar take the downward force as long as the harness goes over the bar? 

I'm not a mechanical engineer so I cannot explain the inertial forces involved.

The best I can explain is that in the correct configuration the restraining forces are horizontal rather than vertical.

Perhaps a more technically minded member can explain it better than I

Seriously ?
