I bought the spec stage three ceramic (429 notes) and paid a local transmiision repair shop here in oklahoma around $675...That covered Installation, a couple of exhaust bolts that had seized and had to be cut off and replaced and 4 qts of Mercon Five Synthetic Tranny Fluid...Along with the cost of the clutch assembly with shipping it totaled right around 1200 dollars...If i had it to do over i would have gone with the Stage three Kevlar as opposed to the Stage three Ceramic...
