Probably posting old pic here, but just to show those 2 camber mount holes:
To access gearbox you need to remove 6 screws. Since the camber mount is attached is to the top cover via the ball stud you also have to detach ball cup. One way to make it easier is to make a hole in the ball cup so you can remove (unscrew) ball stud without removing the ball cup.
Question is if you really can lift that top cover without removing top decks though? The 2 front screws under the top deck can be hard to access. Also, can you lift that top cover past the top deck?
In worst case you have to remove top deck (4 screws) and then another 6 screws to access gearbox.
Yeah, probably does´nt need to remove diffs as often as on the 511, but is is always nice to have a car that is easy/fast to maintain.
Just a few thoughts. Can be wrong, will see when car arrives.
