Sometimes only one front belt in a Mercury Marquis needs replacing. Seatbelt Planet's single belt fits either the driver or passenger position on the front bench and gives it a retracting lap-and-sash belt with a heavy metal pushbutton latch. Mounting hardware comes with it.
Where It Fits
Listed for the driver or passenger front position of 1970-1973 Mercury Marquis models.
Color Options
The Marquis color chart lists 52 webbing shades, 13 premium. Order the same color as the opposite side to keep the bench uniform.
Why Replace Old Belts?
A single belt is an economical fix when one side has a worn strap or a failing latch.
Care Tips
Allow the retractor to wind the strap in without letting it snap back, and clean it with a mild soap solution.
About the 1970-1973 Mercury Marquis Bench
Full-size Mercurys of the early seventies were long, quiet and comfortable, and the Marquis sat at the top of the range. Many were ordered with plush bench seats and power options.
Pre-Install Checklist
Inspect the floor and upper anchor points for the side you are replacing and clean the threads.
Good to Know
One belt for one front position.
Order a second belt later in the same shade to complete the front.
When unbuckled, the reel tucks the chest strap up beside the Marquis door pillar.
Seatbelt Planet makes the belt to order.
A center belt is also available for the middle of the bench.
The metal latch has a satisfying, solid feel.
Ordering one belt at a time works well when the car came to you with a mix of old and replacement belts, or when only the driver side has worn through. You can match the color of a belt you already have, or start fresh and order the other side later.
The Marquis front bench is wide and soft, and a three-point belt with a retractor gives the outboard rider good upper-body restraint without leaving loose webbing on the seat.
Seatbelt Planet rates the belt to FMVSS 209 and 302.
Check the upper anchor location for the shoulder portion on your body style, and clean the threads at both the floor and the pillar before the belt arrives.
Big Mercurys are wonderful highway cars, and a fresh belt makes the driver's seat feel as good as the rest of the cabin.
If you also want the middle of the bench covered, a center belt for these years is listed separately.
A single Marquis belt is a quick, affordable fix for a worn front position.
It suits a classic car driven on weekends.
