Cap, I've got an extra pair if you want them; don't currently have a use/home for them.
As for the looseness issue, it's common with scales that have been repeatedly swapped. A simple solution is to put a small drop of superglue in the divot for the rivet in the scale before you put them on. If you don't use too much, they're still easy to remove, and it keeps them from wiggling around after you've pressed them into place.
Also, I use a small C-clamp to seat them because it lets me very precisely control the amount of pressure applied to get them to seat on the knife.
