There are four sizes. Small for 58mm, large for modern 91mm. But there are also specific springs for 74mm and a different size again for 84mm and old 91mm. You can modify the modern 91mm spring though to fit the 84mm scissors.
The info on the springs comes from Neil and if you need springs for 84mm scissors, he has them, they just aren't listed on edcsource so you'll have to PM him.

Not sure if the shipping cost is going to be expensive.
