That's the size of the later TR4-TR6 rotors; original TR3 rotors were 11".

The TR4-6 mounts also move the caliper closer to the axle, but I'm not sure
by how much.  The calipers changed at the same time, so may not be strictly
comparable.

Not from the factory, although the later mounts will fit on the TR3 vertical
links.

As TeriAnn said, the 4-synchro box is a bit longer than the original
3-synchro, so slot the mounting holes in the rear crossmember.  ISTR I also
rolled down the lip on the crossmember a bit, but that may not always be
required.

Depending on which gearbox, you may also need to fiddle with the clutch
linkage.  I used a late TR6 box with the thicker flange, which moved the
clutch slave back by 1/4" or so.  I had to trim the pushrod to match, and
make a bracket for the return spring.  Also longer studs & bolts for
mounting, but that's trivial.
