As for 8 hrs, given the have to drop the subframe to remove the diff, front axles, and the bolts are hard to reach that doesn't sound too bad.

thanks...not sure what you meant by "What about your diff broke ?"

He means what broke in the diff?

But I am having hard time accepting that 275/40 has the same diameter as 315/35.
The length of the circle is 2PiR
Where We have 275x40, 40mm (4 centimeters) height of the tire which we will add to the diameter of a rim on both sides.... 4+50.8(diameter of the rim)+4= 58.8, where radius would be precisely half, 2 x 3.14 x 29.4 = 184.73
Where we have 315x35... (3.5 centimeters)
3.5+50.8+3.5=181.58

According to that wheel with tire that has a wall height of 40mm will have 184.73cm outer length and the one with 35mm wall height will have 181.58 cm outer length which is not the same.
Am I overthinking the situation?

you are over thinking it

275/40/20 315/35/20 has been my tire size for almost 200,000kms
this is factory
ther is a built in tolerance
check out the tire size for the x6s and new x5s with 21' rims

He isn't over thinking anything, just miscalculating one of the pieces. There aren't so much built in tolerances, but rather those two sizes have nearly the exact same rolling diameter.

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.
