Important Considerations:
* Early vs. Late: While the range is 1983-1997, there might be slight differences between the earliest and latest years in that range. Seats from a 1983 might require more modification for a perfect fit than a seat from a 1992 or 1997.
* Trim Level: Higher trim levels might have different features (power adjustments, heated seats, etc.) that could affect fitment. While the frame should fit, the extra features might not be compatible with your truck's wiring.
* Manual vs. Power: Make sure you're replacing manual seats with manual seats, and power seats with power seats. Direct swaps are easiest.
It's always best to check the specific seat model numbers of the seats you're considering against the model number of your existing seats, or consult a parts store or online forums dedicated to Ford Rangers. Pictures can also be incredibly helpful in comparing the seats.
