This appears to be OEM Ford stuff here: https://www.southfloridafordparts.com/v-1999-ford-taurus--se--3-0l-v6-gas/brakes--anti-lock-brakes Since the 99 is so old, many parts aren't even made for it anymore. Wow, that's too bad. Look at all of the parts on there marked as discontinued.
I'd rather walk than drive that. That is driven by somebody who just didn't care. What a shame. I love manual transmissions. I wish Ford made more manuals in vehicle like this.
