My father took out one "1" link.

Question

Even though it is a stretch band, I am a very small wrist and we take one link out.My problem now is that he did not securely put those pins in when he put the band back together and the band is about to come apart. He can't remember where he laid the spare link so now I have no more pins. The ENDCAPS are goldtone in color. Where can I get the correct length Ecclessi pins for that type watch?
