Fitment Notes
Listed for the front center of 1970-1973 Mercury Marquis models.
Available Colors
52 colors, 13 premium. Match the outboard belts.
Why New Belts Matter
Center belts are often missing in big classic Mercurys. Fresh webbing returns the middle spot to service.
Keeping Them Like New
Leave both halves on top of the cushion and clean with mild soap.
About the Marquis Front Bench
Full-size Mercurys of this era used a wide bench seat with a fold-down armrest in many trims.
Pre-Install Checklist
Find the center anchor points under the bench and clean the threads.
Good to Know
Hardware included.
The maker builds the belt to order.
Raise the armrest to reach the belt.
Pair it with the outboard kit.
Third riders appreciate a working belt.
Classic Marquis owners value complete interiors.
Seatbelt Planet rates this Marquis middle strap to FMVSS 209 and 302.
Marquis benches are wide enough for three adults, and the center position is often used by a child or a third adult on short trips. A fixed belt sized for that spot stays where you set it.
Before ordering, lift the bench or slide it forward and confirm the center anchor holes are intact and in solid metal. Many cars had center belts removed during upholstery work.
The maker builds the belt after the order is placed, in the shade you choose, so it can match the outboard belts in the same order.
The steel push-release latch matches the outer Marquis belts for one latch style across the seat.
Full-size Mercurys of the early seventies are increasingly appreciated as comfortable classic cars, and complete interiors help them show well.
Hardware is included with the belt.
Center front belts on full-size cars were often removed or tucked away under the cushion over the decades, and many are now missing. This replacement gives the middle seat of a Marquis bench a fresh, working strap.
Because it uses the same latch style as the outboard belts, the whole front bench feels uniform.
Choose the webbing color to match your existing front belts or order a full set in one shade.
Look under the cushion for the two center anchor holes and clean their threads before the belt arrives.
Mercury built the Marquis as a comfortable long-distance car, and a complete belt set fits that role well.
Questions about fitment can be answered by calling 574-226-6676.
Owners rebuilding the whole front bench can order the outboard belts at the same time for a perfect color match across all three positions.
