Congrats, glad MOS was able to take care of you.
Warranties do not cover pre-existing issues, after about 3 months of having your policy it is pretty difficult for them to prove something was pre-existing. Not many cover things like clutches, brakes, bushings. These are ware parts and are often identified by name as not covered. There are likely plans that cover these, but would charge more as these are guaranteed to need replacing.
Bushings are pretty easy to do, the clutch sucks as you have to undo one side of the subframe.
