* Online Parts Retailers: Sites like AutoZone, Advance Auto Parts, Napa Auto Parts, or RockAuto allow you to select your vehicle's year, make, and model. Once you select "differential," you should find diagrams, although they might not be as exploded as you'd like. They're often more focused on showing individual parts for sale. Clicking on parts within the diagram might give you more detail.
* Repair Manuals: A Haynes or Chilton repair manual specifically for a 1993 Chevy K1500 will have the most detailed diagrams. These manuals are often available online (sometimes as PDFs, legally or illegally) or from auto parts stores. A factory service manual from GM (if you can find one) would be even better, but these can be expensive.
* GM Dealer: Your local GM dealership might have access to digital parts catalogs with exploded views, though they may be reluctant to share them unless you're buying parts.
* Online Forums: Search forums dedicated to Chevy trucks or automotive repair. Someone may have posted a diagram or a link to one. Be aware that the quality and accuracy of information on forums can vary.
Remember to specify the exact type of differential your truck has (e.g., the gear ratio) as this will affect the exact parts included. The information found on parts retailer websites will usually guide you to finding the correct parts based on your truck's specifications.
