Can't comment on the going prices But I have a good idea on what you'll need
1. Trans (Obvious)
2. Trans crossmember
3. Shifter
4. Flywheel
5. Pressure Plate
6. Clutch
7. Clutch slave
8. Clutch brake line
9. Clutch master cylinder
10. Clutch pedal
11. Driveshaft
Try looking for a wrecked manual trans Z at a local salvage yard
This way you strip it yourself and get everything you need to make the transfer in one shot.
Good Luck
