As som99 and amiman99 said, it should be fairly simple if you have soldering experience, desoldering is the tricky part (especially if some of the pins are tied to a copper plane, as the plane will act like a heatsink, cooling the solder)
If I hazard a guess though, there may not need to be any soldering involved. It appears as though they're using standard machined-pin break-away headers to plug onto existing pins on the card (acting like pin extenders)...Maybe
Can you post a photo of the other side of the card? Failing that, DigiKey or Mouser should have what you're after
I'm in Sydney, Australia - won't be feasible to send it over here, but I'm willing to look at it if you have no other choices available.
