Clutch install, how long should it take?

My car is at the dealer for a clutch change. How long should it take? My girlfriend noticed it went in the shop today around noon and I called before they closed today at 5 and they said it should be ready around noon tomorrow. I'm getting new tires and a safety inspection too so is this a reasonable time frame? I've heard guys say they can change a clutch in less than 3 hours at the track

Well I got my car back and Ford had disappointed me once again. As soon as I left the dealership I heard a major exhaust leak and another weird noise from front end. I tuned in the driveway beside the dealer and went right back to the shop. The Foreman and I drove around the dealership yard and looked it all over and it turned out that the mechanic forgot to put the bolt back in the steel rod that runs from passenger to driver side under the front of the transmission. One end was connected and the other end was swaying back and forth hitting the underside of the car. Since all the mechanics were our the door already (quitting time) the Foreman took it in and bolted it up for me and told me to drop it off Monday so they could fix the exhaust leak. To top it off the mechanic got crap on my seat too but the Foreman said he would take care of that on Monday too. Sorry for the big rant but this really pi$$es me off I watched the mechanic test drive my car before they released it to me and I even spoke with him and he said the car sounded great Either he's deaf or used to work for John Deer and doesn't realise Mustangs shouldn't sound like a tractor
