So I guess you're too picky for Buford dial from Mochacha. Maybe Mochacha could make you a plain 5517 dial. 5517s ran from 1971-1979 so the dial print is white.
The Dark Lord makes earlier gilt dials but I don't know how to get in touch with him and besides, he'd be wrong for a later white print Sub dial probably.
The key to a good 5517 is going to be in the aging of the dial and hands- making the lume look good- yellow but not too yellow. Aging the case is also important.
You might also talk to Tripdog and see what he suggests.
Ruby has dials and Yuki might still be around.
