Do you have to remove the entire bellhousing to install a Twin Disk Clutch such as the Mcleod in a C5 Corvette? All of the diy guides show the clutch being installed through the flywheel inspection cover. Is a twin disk to big to fit through the inspection hole? Removing the entire bellhousing looks like a major pita!

 

Not sure about the twin disk but this link has a lot of good pictures:
