Van Knowledge: How to Identify Parts for Your Dodge B300

Vintage Dodge vans like the B100, B200, and B300 are known for their unique mix of utility and character. But when you're searching for replacement parts—especially interior switches, speedometers, or side glass—knowing your exact model and generation is crucial.

1. Start with the VIN

The VIN (Vehicle Identification Number) on your B300 holds the key. Look for it on the dashboard near the windshield or inside the driver-side door frame. The 5th digit often identifies engine type, and the 10th digit reveals the model year.

2. Know the Generations

• 1971–1977: First-gen boxier vans with round headlights
• 1978–1993: Second-gen, more aerodynamic nose, square lamps
• 1994–2003: Modernized Ram Van era

This helps narrow down what parts fit—especially for dashboards, wiring harnesses, and trim.

3. Compare Part Numbers

OEM part numbers (often stamped or labeled on the item) are your best friend. At OnlyVans, we list known part numbers in each eBay listing to help match your exact needs.
