I have just replaced flywheel, clutch kit, installed SSK shifter on my car by my self on my driveway. If the difference only gearbox vs auto, no way it takes 8 hrs. 6 bolts for both driveshafts, 5 for crossmember with mount and 6 very convenient bolts that hold diffetential to trany ( there are no tricky/inconvenient ones - transmission to engine connection - yes but not differential), oh, and 2 connectors.
