Ok, I broke my chainstay a week ago and the new part came in today. I was trying to take off the broken chainstay and the non-drive side came off by just unscrewingn the fastener. The drive side is a different story. I took off the chainrings but I'm still stumped. I ended up leaving it with the LBS but I'd like to know how to take chainstay off just in case.

Anyone know how to take the chainstay off?
btw the bike is an '03 Dawg.
