Quick answer: Confirm blade length for each position, the actual arm attachment and width, the correct adapter, and clearance across the windshield. Driver and passenger blades may use different lengths.
Check every position separately
Record driver, passenger, and rear blade lengths rather than assuming a matched pair. Compare the installed arms and note whether they have been changed.
What determines wiper fit
- Blade length for the exact position
- J-hook, pin, bayonet, push-button, side-lock, or other attachment
- Arm width and adapter compatibility
- Front versus rear application
- Blade profile and windshield curvature
- Clearance from trim and the other blade
Classic and unusual vehicles
Older cars may have nonstandard arms, refill-style blades, or components replaced during restoration. Measure what is installed and identify the attachment rather than relying only on a modern catalog.
Before buying
Use the vehicle application as a starting point, then compare the attachment shown by the manufacturer with the arm on the car. A universal adapter assortment still needs to match the actual arm.
Save what actually fits.
Record successful blade sizes, attachment types, and part numbers with the vehicle in WrenchFit so the next replacement is easier.
