Hi Rob and welcome aboard ... now as for your request ... that's going to be tough ... if you want to make the ROTS Reveal you could use the MR Darth Vader ROTS which already has the squares for the dynodes . . . if it is the ROTJ version you want perhaps try and upgrade an existing Darth Ugly ROTJ with a new top mount ... there's no sellers I'm aware of that cast only the Reveal ROTJ.
Also try your request at the SLD http://forum.501stsithlords.com/index.php?act=idx become a member and post your intro which will give you access to the Sales section for a WTB ... you can also use the WTB section in our Junkyard ... or perhaps find one here : http://thepropden.aokforums.com/index.php Sometimes you'll find one on ebay but for quite a lot of $$$ when 'finished' however I doubt the level of accuracy, if that's what your after ... So alas, being in the long process of making one myself, it seems the golden age for Reveal parts and makers is nearing an end :cry
