10 3/4 to 11 3/4 front brake upgrade,what do i need??

Caliper is the same.
All you need is the bigger rotor and the larger caliper mounting brackets.
Mopar 11.75" Disc Brake Slider Caliper Brackets
You won't even need to re-bleed your brakes, just swap the rotors and brackets, should be able to do it in about an hour if that.
