Quoted from Lermods:Great to hear. If they are like the ones from pancon, They can be cut to length very easily with a dremel.
1) Ed already said they are not going to be like the ones from Pancon.
2) I use a razor knife myself, they separate pretty easy.
3) If the right size isn't available, I'll just pull the extra pins on a larger one and reduce in size with the belt sander. I have done this a few times in the past.
