Getting 1680 to all original parts

[yld2rob]

So as many of you know, with your great input, I pulled the trigger on a 71' 1680 red sub. The watch came with triple lock crown instead of a twin lock. Can some one give me the part number for the twin lock crown for this model? Is this the only part needed or do I need a new crown tube as well?

The other part I need to acquire is a 9315 bracelet from 71-73 in decent shape. I see this going to be expensive and hard to find.
