Brake Parts Question

[kdog_x]

So I finally tracked my leak down to the proportioning valve under the master cylinder. It's leaking through the front rubber seal at about a thimble full per day .

I called around today to get a price on replacing it, after calling Autozone, carquest, pep boys, and murrays they all told me that they dont stock them and can't order them. Is this a dealer only part, If so does anyone know what they cost?

I searched online but this is all I came up with

Is this the same part?

thanks

Well i dunno how u feel bout going to a boneyard but my mustang has lots of boneyard parts on it and runs really well. I would tromp thru mud to save a few dollas. Other than that try your local ford dealership. I was suprised by what they could get me when i asked (like the light lenses for my license plate) Good luck
