However, you can piece together the information from several sources:
* Owner's Manual: This is the best place to start. While it won't have *every* spec, it contains many key details about your specific truck if you have a copy or can find one online for the correct year and options. eBay and online used parts sites sometimes sell them.
* Factory Service Manuals: These manuals, often available through sites selling automotive repair information (like Haynes or Chilton, though finding one specifically for an '89 D150 might be challenging), provide very detailed technical information, including specifications.
* Online Forums and Communities: Dodge truck enthusiast forums (search for "Dodge D150 forum" or similar) are excellent resources. Someone may have scanned specifications from brochures or other documents.
* Parts Websites: Websites selling parts for classic Dodge trucks (like LMC Truck, for example) might list specifications in their part descriptions or catalogs, although it won't be consolidated. Searching for parts related to your specific engine and transmission will reveal information about them.
* Original Brochures and Sales Literature: These are increasingly difficult to find, but searching online marketplaces or classic car websites may yield results. These brochures often provide a summary of available options and their specifications.
In short, you'll need to do some detective work and collect information from multiple sources to compile a complete set of specifications for your specific 1989 Dodge D150. Remember to always specify the exact engine size and trim level when searching for information.
