There is a ton of bad information in this thread.
The rear disc option was ended in 1999 except for the station wagons.
The station wagon hardware will not fit.
You need the set up off an ABS Taurus and any of them will fit.
I spent an hour and half pulling the parts in a salvage.
And maybe an hour a side pulling the drums and all its related hardware and hoses and rerouting cables and installinng all the new hardware when I did the install.
You need the pie tins, backing plate ,hoses,hub/bearing,rotors,brackets,calipers,pads
Ebrake cables and prefferably the abs sensors.
This can all be had out of a Donor car for under a hundred dollars.
A lot of people have done this conversion on the 2000 and up including me and it was well worth the effort.
I did notice an increase in stopping power and the abs system works fine.
You dont have to change any computers ,modules or anything other than adding the correct ABS Sensors.
