Dual extruder swing arm files

I need to print new lever arm pieces because my filament has worn its own channel next to the bearing and started popping out instead of being pushed against the hobbed extruder wheel. I have a dual extruders and the file I found titled 'new swing arm front plate_v1.0.stl' is only good for the right extruder. I need the mirror image of this part for the left extruder. Is this other file available or will I have to make my own?
