driving around after work today getting bits & pieces for upcoming turbo install

got to a point where clutch almost all the way out before it would engage drive, stopped and checked if it still had clutch fluid - yep. went to take off and now won't go anywhere

so at the moment it is parked in town and will get a tow off a mate later tonight.
can select and gear. push clutch in, feels real spongy, select first, release clutch and push in accelerator. don't go anywhere, car just sits there and revs

i'm thinking its the clutch/maybe clutch slave cyclinder ??? do people agree and should I have it towed home and pull gearbox & clutch out and check it myself or ....?
bloody



Cheers
