I just did a new clutch when I put the turbo engine in my 240. It is very straight forward, just like any other clutch. I had both the engine and tranny out of the car. I was too cheap to buy an alignment tool, so I very lightly tightened down the pressure plate and used the whole transmission to align the clutch, then pulled the tranny off and tightened down the pressure plate bolts a quarter turn at a time. I disconnected the clutch line at the firewall, but it only took about 10 min to bleed it when I was finished. The PO told me that it the car had had recent clutch work and the throw out bearing looked new so I re-used it and did not have the flywheel resurfaced. I did use some 600 grit emery cloth to rough up the face of the flywheel and pressure plate though. I also put a new pilot bearing in too. Pry off the dust cover, remove the old one, grease the new one, tap it in place and tap the dust cover back on. It’s easy
Good Luck.
