I had the same oegal issue wirh the need to keep the ABS brakes on my ZJ when I did the WJ brake & knuckle swap. It is fairly easy actually; I cut a custom 1/4" thick spacer plate for the caliper brackets, of which I used to mount the ABS wheel speed sensors to. Also required is to drill an 18mm hole to the knuckle for the sensor, and a bit of dremeling on the sensors. IRC I've got some pictures of this on my ZJ build thread. ABS has been working perfectly ever since
Worth it? Definitely. You'll love the added stopping power and much better steering
