Service bulletin WP60-100

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Western Star Parts Technical Bulletin for Universal Design Floor Mats. Universal floor mat designs fit multiple cab configurations and may require trimming. Trim lines displaying size options are scored into the pad side of the mat; use an existing floor mat as a guide for optimal results. The new mat should not interfere with safety-critical equipment, such as foot pedals.

The document
