Clean the webbing with mild soap, let it rewind gently, and keep it out of the door jamb.
About the 1970-1973 Mercury Marquis
The Marquis was Mercury's top full-size line, sharing its body with the Ford LTD but adding hidden headlights and plusher trim. Brougham and Colony Park wagon versions were offered.
Pre-Install Checklist
Inspect the floor and upper anchors on both sides and clean the threads. Shoulder belts need solid upper mounting points.
Good to Know
Hardware included.
Seatbelt Planet sews and checks both belts to order.
A center belt is listed separately.
Big Mercurys are smooth highway cruisers, and shoulder belts make long trips more comfortable.
Matching the interior color keeps the cabin looking original.
Brougham interiors with plush cloth benches suit softer webbing colors.
Classic full-size Mercurys are gaining collector interest.
Compare the listing photo with your car before ordering.
The Marquis kit is rated to federal standards 209 and 302, per Seatbelt Planet.
Full-size Mercurys of this era have long doors and wide front seats, and retractable shoulder belts keep the straps close to the pillars so they never hang in the door opening.
Before ordering, confirm your car has upper anchor points for shoulder belts and clean their threads along with the floor anchors.
Seatbelt Planet sews and checks both belts in one webbing color after you order, so they arrive matched.
The Marquis Brougham's plush interior looks best with belts in a coordinating shade.
Big Mercurys like the Marquis are excellent highway cruisers, and three-point belts add peace of mind on long trips.
The Marquis was Mercury's full-size flagship, a long and heavy car with a wide front bench. Three-point belts give the driver and front passenger far more upper-body restraint than the original lap belts did.
Big Mercurys like this make wonderful highway cruisers, and modern-style belts help make them comfortable to drive regularly.
Pick a webbing color that suits the cloth or vinyl upholstery used in your Marquis.
Check that your car has the standard front bench layout before ordering.
