That's a tedious job; I'm sure any of the members who have the skills to instal one of the springs have the ability to cut them down to length. I wouldn't add to your workload.
Boltcutters are an imprecise tool, I'd fashion a small wooden block with a groove for the spring to locate in, making the thickness of the block act as the guide for a dremel cutoff blade.
I'll take 2, when you're ready.
