I attempted a similar conversion some time ago.
I couldn't find a cheap converted so I attempted to re-wired it by hand, 
a pinout is at:

The monitor was a Sun GDM-1662B.

The first attempt was very poorly done, wiring directly into the case. 
It worked enough to tell me that I was on the right track.
My second attempt is to join the middle of two cables, but I haven't had 
the time to finish it.

One thing you also have to bare in mind is that it is a fixed refresh 
rate.  I was going into my PC and used the following mode-line.
Mode "1280x1024"
         DotClock 82
         HTimings 1024 1112 1192 1224
         VTimings 768 776 784 932
         Flags "+hsync" "+vsync"
Not sure if its correct, from memory I calculated them myself.
