We stock only automotive clips, retainers, and fasteners — this is our entire business. Bulk packs ship same business day, so you're never waiting on a back-ordered bag of clips to finish a job. What's the difference between 18249 (6503339) and 18247 (6503336)? Both are Chrysler/Dodge cowl retainers but they serve different functions. The 18247 (6503336) is a push-pin cowl screen retainer that holds the cowl vent screen in the channel. The 18249 (6503339) is a stud cover that snaps over an exposed threaded stud post on the cowl grille panel. They are not interchangeable. How many does one vehicle need? Most Dodge Ram, Durango, and Dakota cowl panels use 4–8 of these stud covers. We recommend replacing the full set at once — they're inexpensive and become brittle over time, so the ones you leave in place will likely fail at the next service. Is this OEM quality? Yes — this is a direct equivalent to Mopar 6503339, made to the same nylon specification. It's the same part used by dealers and body shops to restock after cowl panel repairs. How do I install it? Push straight down over the exposed cowl stud post until the clip snaps into the locked position. No tools required for installation. To remove, use a T30 Torx bit to unscrew, or carefully pry up from the base with a trim removal tool. Do you offer volume pricing? Yes — available in 25, 50, 100, and 150-piece packs. Per-unit cost decreases at higher quantities. The 100-piece pack is ideal for shops regularly servicing Dodge and Jeep vehicles.
