Before you fork out all the $$$$ for a new clutch, make sure that's what is really the cause of your slipping.
A clutch slave rod that doesn't completely release the clutch can cause your clutch to slip. Easy to check. Crawl underneath and have the clutch pedal depressed. Then watch when the clutch is released. If the clutch fork doesn't travel all the way back, then all you'll need to do is shorten the slave rod.
I had it happen to me. Easy fix.
