If the case etc is rep, I would consider buying Josh's 5513 and robbing the bezel, insert and bracelet from that. If the case is gen, I would scour The Vintage Rolex forum and buy a gen bezel and insert, they come up pretty often. The bracelet, I would use from the Josh 5513, it's not bad at all and if you like, you could add a gen clasp to it. Any gen parts on the bracelet on that watch... you can sell to recoup some money.
It's pretty hard to figure what to do.. without knowing the value or gen parts of what you have. When does it arrive?
