2001 Spectra clutch repacement

Anyone ever replaced a clutch on a 2001 spectra? similar i guess to the sephia - mine's a 1.8L, 5 sp of course. the clutch (it feels) is beginning to 'chatter' on takeoffs when it's warmed up or in stop/go traffic. it's got 77000 miles - not sure how long these things last...
