LeeLandTeeslink Ideally a RWD AX15 to start with. Making a RWD from a 4WD would require the correct rear housing assembly and output/mainshaft. Internals other than the mainshaft would be common. Noting also the differences between the input shaft pilot tip diameter and internal or external slave cylinder options.
Other items you may need would be the hydraulic clutch components and pedal assembly (if replacing and automatic) PCM re-programming may also need to be addressed.
