What is the width of the rear end of a 1949 Mercury?
The rear end width of a 1949 Mercury is typically described in two ways: the rear track width (the distance between the centers of the rear wheels) and the overall body width across the rear fenders. In practice, the rear track is about 56 inches, and the body width spans roughly 69–70 inches.
Understanding what width means for a 1949 Mercury
In classic car terminology, “width” can refer to how far apart the rear wheels sit (track) and how wide the body is from edge to edge at the rear. Both figures are useful for wheel and tire fitment, suspension alignment, and clearance around doors and bumpers. Below are the most commonly cited measurements for the year and model range.
Rear track width
Rear track width is the horizontal distance between the centers of the two rear wheel hubs. For most 1949 Mercurys, this figure sits around 56 inches (about 142 cm), with minor variations depending on trim and axle assembly.
Below are the primary width measurements you would encounter when assessing a 1949 Mercury’s rear end.
- Rear track width (center-to-center between rear wheels): approximately 56 inches (about 142 cm).
- Notes: Small variations can occur due to differing axle/brake configurations or aftermarket components.
The rear track width is the key specification for wheel fitment and suspension geometry, and it remains the most frequently referenced dimension when discussing the car’s rear end width.
Overall body width across the rear
The overall body width, measured from the outer edge of one rear fender to the outer edge of the other, is typically about 69–70 inches (roughly 175–178 cm). This range covers most 1949 Mercury sedan and coupe configurations, though exact figures can vary slightly by model and bumper setup.
Below is the primary width measurement you would encounter for the exterior width at the rear of the car.
- Overall width (fender-to-fender): approximately 69–70 inches (about 175–178 cm).
Body width is especially relevant for garage clearance, bodywork alignment, and bumper fitting; as with track width, there can be small deviations based on body style and factory options.
Verifying the measurements on your specific vehicle
Because production tolerances and aftermarket modifications can affect exact dimensions, it’s best to confirm with direct measurements or manufacturer documentation when precision matters.
- Identify the specific model and year details (for example, Mercury Eight, Mercury Custom, or other 1949 Mercury variants) and locate the factory service manual or build sheet for that configuration.
- To measure rear track width, measure the distance between the centers of the rear wheel hubs or drum mounting surfaces with the wheels installed and the car on a level surface.
- To measure overall rear width, measure straight across from the outer edge of the left rear fender to the outer edge of the right rear fender at a consistent height (near the bumper line) to capture carrier and bumper variations.
- Record the measurements and compare them to the typical ranges (approximately 56 inches for track width and 69–70 inches for overall width). If you see deviations beyond a quarter to half an inch, re-check measurement points and tool accuracy.
Accurate verification helps especially for wheel/tender fitment, custom builds, and parts sourcing where exact width specs matter.
Summary
For a 1949 Mercury, the rear end width is typically characterized by a rear track width of about 56 inches and an overall body width across the rear of roughly 69–70 inches. These figures guide wheel choices, suspension setup, and clearance planning, but variations can occur by model, trim, and aftermarket modifications. Always confirm on your specific vehicle with direct measurements or the original factory documentation.
