I'm pretty sure I've got a couple candidate bikes in that 58-59 size you are looking for. I'm out of town until Sunday. When I get back home I can dive into the garage with a camera and a tape measure. I think I'm headed out to Bigbossman's place (and El Cerrito as well) sometime early next week, so I can bring anything you might be interested in out that way.
BBM, let me know if you need any parts for those Nishiki frames for those builds. I can check the usual and unusual places out here. And I've still got that bunch of cable housing I'm gonna bring out to you.
