Im busy removing my ABS, I'll re-pipe the whole car. Looking at some threads/sites some people just by pass the modulator and keep the ABS master cylinder. Basically at the moment it goes from the master cylinder through a abs pump then to the 3 way connector on the front inner wing. Some people just fit a new pipe from the master cylinder to the 3 way connector on the wing. Not sure how effective it is though, but its hell of alot easier.
