The 1998 Chevy Tracker typically has two different types of drive shafts, depending on whether the vehicle is a two-wheel drive (2WD) or four-wheel drive (4WD) model. The 2WD version uses a simpler drive shaft configuration, while the 4WD model features a more complex setup to accommodate its all-wheel drive capabilities. Additionally, variations in length and design may exist based on engine options and production dates. Always consult a parts catalog or dealership for specific part numbers.
To change the clutch in a 2002 Chevy Tracker, first, raise the vehicle and securely support it on jack stands. Remove the transmission by disconnecting the drive shafts, exhaust, and any electrical connections, then unbolt the transmission from the engine. Once the transmission is out, replace the old clutch components (pressure plate, disc, and release bearing) with new ones, ensuring proper alignment. Finally, reassemble the transmission and related components, and check the clutch operation before lowering the vehicle.

It would depend on what equipment and tools you have available.
