slave cylinder? these cars dont have hydraulic clutches.
you will need the whole pedal assembly, cables, cable brackets, shifter, console, the trans and the driver side trans mount along with the rear support (bobble strut). the auto ecu will make the car seem like it is going to stall when you stop hard, it will run the car but you should grab the 5 speed ecu.
your axels will be fine although the factory 5 speeds use a equal length axle setup with a intermittent shaft that bolts to the block.
