Call three different shops and get an estimate on the repair as they might vary just a little, it's done by the book hour and is calculated in 6 tenths of an hour for labor operations. You'll have machining, parts replacement, labor units and wear items replaced. You will also need an alignment.
It`s a job best left to the "Clutch doctors" or such shop like that (one that only does clutches).
tell him you have to seperate the engine and transmission to do that, and a Clutch shop can do the whole job in less than 3 hours, have the tools to do it right as ALL they do is clutches, and shouldn`t cost more than $250 for the whole thing.
