* Auto parts stores: Places like AutoZone, Advance Auto Parts, NAPA, and O'Reilly Auto Parts will stock common parts for these trucks.
* Online retailers: Amazon, eBay, and numerous online auto parts specialists often have a wide selection, including new and used parts.
* Junkyards/Salvage yards: This is a great option for finding used parts, often at a lower cost.
However, for the earlier model years (pre-1990s), parts can become more difficult to find, and the used market becomes increasingly important. Some parts might be discontinued by the manufacturer, requiring more searching or potentially custom fabrication.
In short: Yes, for many S-10s, parts are readily available. But the ease of finding parts will depend significantly on the model year.
