HELP! Road Runner in prison, or any garage door repair guys out there?

It is a very dangerous job, I was an overhead door serviceman for a short time, until a nasty injury from a ladder fall left me with 2 broken wrists, 3 broken teeth and a serious concussion. If you haven't done it before I really recommend not trying it DIY. I would gladly help you out, but being on the north side of the border prevents that from happening. It is also critical to have the exact measurements of the wire size, diameter, and overall length to ensure you get the correct replacement spring for the size and weight of your door. Sorry, I know it's not what you want to hear.
