Ah, good call—for some reason, I hadn't thought of sanding down the pivots. Guess I'll have to order another set. As far as setting the springs, that wasn't very difficult at all. The "close the tool, stick them in, and beat them with a hammer" method worked like a champ!
The knifekits ones are horrible spec lately. I highly recommend the ones from alpha knife supply. I used those on a juice mod and didn't have to do anything to the tool pivot holes.
