Chris, IMHO 12.7 stands for max thickness for the disc
Pads 16mm is also max thickness for the pads.
Even if your disc is 9.6 the steel pins will still support the pads, i do not think there is a problem.
The difference is 1.5mm on one side, if this would cause problems for the pads on 9.6mm disc's you would have the same problems with 12.7 disc's.
I think that the pad code is MDB1200.
