Parts that are *likely* interchangeable:
* Engine parts: If the engines are the same (e.g., 4.3L V6), many internal parts will be interchangeable. However, even then, some minor differences might exist.
* Suspension components: Many suspension parts, like springs, shocks, and control arms, are often interchangeable.
* Interior parts: Many interior components, like door panels, seats (though fit may vary slightly), and some dash components may swap over.
* Body parts (with caveats): Some body panels might interchange, but there's a higher chance of fitment issues than with mechanical parts. Minor differences in styling could lead to incompatibility.
Parts that might be *problematic*:
* Wiring harnesses: Wiring harnesses can differ, especially if options or features varied between the two model years.
* Computer modules (PCM/ECM): These are often year-specific and will likely not be interchangeable.
* Specific trim pieces: Minor styling differences between the years may mean some trim pieces won't fit.
Recommendation:
Before purchasing any used parts, it's best to:
1. Verify the part numbers: Compare the part numbers from the 1997 S10 to the part numbers for your 1994 S10 using a parts catalog (like a dealer's online parts catalog or an online auto parts store's catalog).
2. Check online forums: Search S10 forums (like S10 Forum or other enthusiast sites) for discussions about swapping parts between these years. Someone may have already tackled the specific part you're interested in.
3. Check the parts visually: If you're buying used parts in person, carefully compare them to your existing parts to ensure they are a good match.
In short, while many parts *will* fit, always double-check compatibility before committing to a purchase.
