Same Car, Different Parts? Why Window Moldings Are Not Always Interchangeable | Honda Accord CU2 vs CW2 Case Study
Same Generation Does Not Always Mean Same Parts
When replacing exterior trim parts such as:
- Window moldings
- Beltline weatherstrips
- Door outer channel trims
- Chrome delete trims
many customers assume:
"If the vehicle is the same generation, the parts should fit."
Unfortunately, exterior parts do not work that way.
Unlike engine components that are often identified by engine code, exterior components are heavily dependent on vehicle geometry.
A perfect example is the:
- Honda Accord Euro CU2 Sedan (2008–2015)
- Honda Accord Euro CW2 Tourer / Wagon (2008–2015)
- Acura TSX Second Generation (2009–2014)
Although these models share the same platform family, the rear door window moldings are different.

Why Do Front Window Moldings Fit?
Honda designed these models with a high level of component sharing.
From the front doors forward, the vehicles share many identical components:
- Hood
- Front fenders
- Front doors
- A-pillars
- Front glass structure
Therefore, the front outer window moldings are commonly interchangeable.
Example:
| Position | CU2 Sedan | CW2 Tourer |
|---|---|---|
| Front Right | 72410-TL0-003 | 72410-TL0-003 |
| Front Left | 72450-TL0-003 | 72450-TL0-003 |
These front trims belong to the same application group.
Why Rear Window Moldings Are Different
The difference begins behind the B-pillar.
CU2 Sedan Design
The sedan uses:
- Sloping C-pillar
- Shorter rear door glass area
- Separate trunk design
- Different rear window angle

CW2 Tourer Design
The wagon/tourer requires:
- Extended roofline
- Larger cargo opening
- Different rear glass shape
- Different rear door frame geometry
Although the front doors are similar, the rear door structure is different.
Therefore:
The rear window molding profile, length, and curvature must also change.

Why Exterior Parts Are More Difficult Than Mechanical Parts
For engine parts, compatibility usually depends on:
- Engine code
- Transmission code
- OEM number
For exterior parts, compatibility depends on:
- Body style
- Door structure
- Glass curvature
- Roofline design
- Production market
A difference of only a few millimeters can cause:
- Incorrect clip alignment
- Poor sealing
- Wind noise
- Water leakage
- Visible gaps
This is why window moldings are among the most misunderstood aftermarket parts.
