Welcome to our forum.
I've replaced all mine, used a kit similar to what Zep posted. Felt kinda strange cutting the clips, but the only other possibility is to undo and resew the strap- which is out of the question.
Brewman, Watcha use to cut the notch? snip it or saw it?
Just us a laser beam for cryin' out loud!!
If I recall, I used a utility knife. The plastic cut relatively easy. Coulnd't find the laser, Dr. Evil must have not yet returned it. That's what I get for lending my tools to someone named Dr. Evil.
bored at work.
