In reply to lithos:
I've been searching for ages to fix broken plastic buckles on one of my packs. They are pretty hard to come by in the desired size!
The only individual ones I can find are from Mad Rock, Metolius, Cactus Climbing, Alpkit and ITW G-hooks or they come as part of compression straps. But they're mostly all in 1" webbing size which is too big!
Its strange they're so hard to come by, as they're becoming very popular. I tried contacting a few manufacturers asking if they would sell some spare parts as bulk to no avail.
