Another alternative is to fit a disc brake adapter that is 1.37x24TPI threaded and will therefore attach to the fixed side of a flipflop hub.
Not much use when the OP stated they wanted a 135mm hub. Trying to make a track hub fit a 135mm frame with anything approaching decent chainline is a fool’s errand.
