Anyone parting out a 91-93 3.3 liter with ABS?

My ABS went out and the dealer replaced it under a recall... unfortunately, the pump keeps running and I was told it the "dual pressure function switch." They want almost $500 to replace it so I've been trying to find a used one and it's been impossible so far.

Anyone parting one out? Or does anyone have a good pull-a-part nearby? I'll make it worth your while... (and I'm good for it if you want to ask at stratusphere.net about me.)

Thanks in advance for any help or tips.
