G'day all. The old ED's clutch is on its last legs and i'm just wondering what i'll be looking at paying for a new one. What actually needs to be done and how long should it take? I'm asking so I have a rough idea if the mechanic is overcharging or if theyre on the level.

P.S. The falcon is an XR6 which was converted from auto to manual. As far as I know it was just the falcon parts which they stuck in. The diff is apparently still running the auto ratio though. Will this be a problem for the mechanic?
