Oldsmobile/Buick Repair: rear anti lock brakes 93 buick, buick regal gs, drum brakes

Question
I have a 93 buick regal gs with 4 wheel anti lock brakes how difficult is it to change myself, have some experience with disc brakes myself though no anti lock any info would be helpful. thanks

Answer
Hi Scott,
Just jump right in there. You probably won't even see any antilock parts. All there is back there is a wheel speed sensor, and it is behind the backing plate.
I really kinda think you have drum brakes back there, but if they are discs, so much the easier.
