Salvage yards often have used truck parts, including body parts, interior and trim parts, glass and mirrors and even transmissions and engines. Have a plan before visiting a salvage yard to avoid getting overwhelmed by the large array of parts.
Begin by researching a few salvage yards in the local area. Call the yard before hand, and inquire about available stock to avoid wasting time looking for unavailable parts. Some salvage yards make their inventory available online.
Negotiate the price before pulling the part. Most salvage yards have a price board with common parts listed, usually in the yard office. Customers must pull parts and do the heavy lifting. Negotiating beforehand offers more leverage, as people generally do not want to leave parts that they have worked hard to retrieve despite the price.
