Broken part inside SRAM CX-1 shifter

My SRAM Force CX-1 DoubleTap w/ hydraulic reservior, 11-speed has a broken cable holder/tensioner thing on the inside of the shifter. I can probably figure out how to take it apart to get the broken piece out but does anyone know where I can buy the replacement part? Also, for anyone who has experienced this, will I be able to replace this part/fix this shifter without having to disconnect the hydraulic line?
