The recall has long since expired.
But there are options out there.
If you can remove the electronic portion of the ABS module from the van, there are services out there that can repair the module. Search eBay for "Windstar ABS repair" for examples. They are currently asking upwards of $100 for this service (and some offer it for much less).
Note that you can drive the van without the ABS electronics in place (of course, the ABS won't work). The hydraulic portion is still intact. Separating the electronic portion from the hydraulic portion - without removing the whole unit - will be difficult if there's a lot of corrosion on the underside of the van. The ABS unit is on the bottom of the van, basically below the driver's seat. The electronic portion is attached to the hydraulic portion with 6 steel bolts - that are threaded into the hydraulic unit's aluminum structure. This automatically creates the potential for corrosion that can make the fasteners difficult to remove without destroying them.
I suspect modules may be interchangeable - but don't know about specific model year limitations, etc.
