Hmmm, well this could be an opportunity to kill 2 birds with 1 stone and bin the ABS at the same time.
If your clutch is slipping its going to need doing sooner or later. Its not tooooooo bad doing a clutch, hardest part for me as always is popping the N/S drive shaft out and getting the main shaft relocated.
It would probably benefit you in the long term to fit an uprated clutch and the MK6 pedal, should be all good then
