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.
