No ABS on a solid axle swap. Nowhere to mount the sensors on a Dana 44.

No sway bars on a SAS. Unless you wanted to go with an Anti-Rock bar then sure. But really, if you set up the coilovers correctly, with the correct springs and valving, then in reality, I wouldn't use anything.

Besides, with a SAS, you're making the commitment from mall crawler to rock crawler. Some give and take is necessary.

Besides, you can offset some of the cost of the swap by selling your ABS Module and sensors.
