Here's why:
* Drivetrain Components: The drivetrain components, including the transmission, rear axle, and driveshafts, are generally the same for different cab configurations within the same model year and engine/transmission setup.
* Wheelbase: While the extended cab has a longer wheelbase, the driveshaft length is primarily determined by the distance between the transmission and the rear axle, which is likely the same for both configurations.
Important Considerations:
* Double Check: To be absolutely sure, it's always best to double-check with a reputable parts supplier or a Chevrolet dealer, providing your vehicle's VIN for accurate identification.
* Specific Components: There might be very slight variations in some components, like the U-joints, due to different manufacturer specifications or aftermarket modifications. However, the core driveshaft itself is likely the same.
In Conclusion: It's highly probable that the driveshafts used in a 1998 S-10 4-cylinder 5-speed with regular or extended cab configurations are the same. However, always confirm with a trusted source to be sure before purchasing.
