Westone Spectrum SX complete tremolo replacement options

Just bought a westone with no tremolo at all. I see it came with a Bendmaster FT originally but from the searching I have done, I am going to be hard pressed to find one. Has anyone replaced the entire tremolo with an aftermarket one? I was looking at this one http://cgi.ebay.com/CHROME-TREMOLO-GUITAR-BRIDGE-ELECTRIC-GUITAR-/220512061615?cmd=ViewItem&pt=Guitar_Accessories&hash=item33578b08af looks a lot like my PRS SE , seems wide at 2-1/8, Looks liek the SX needs a 2" distance between top to bottom E but can someone confirm this. And of course if someone is sellinf a bendmaster complete setup that will fit I would be happy to purchase it.
Thanks in advance , would love to get this thing up and playing.
