* Online marketplaces: Sites like eBay, Amazon, and Facebook Marketplace often have used owner's manuals for sale. Search for "1990 Ford Mustang 5.0 owner's manual." Be aware of prices – condition will greatly impact the cost.
* Ford dealerships (long shot): While unlikely, some dealerships might have access to older manuals or be able to order a reprint if they have the part number. It's worth a call to a few local dealerships.
* Online Ford parts websites: Some websites specializing in Ford parts might offer reproduction manuals. Check their catalogs.
* Specialty car parts retailers: Stores that focus on classic or muscle cars might carry reproduction manuals or have leads on used ones.
* Repair manual sites: While not exactly an owner's manual, a repair manual (like those from Haynes or Chilton) will provide detailed information on your car's systems and maintenance. These are readily available online and in auto parts stores.
Important Note: When searching online, be sure to specify "1990 Ford Mustang 5.0" to get the correct manual. The manuals can vary slightly year to year and by trim level.
