I posted a DIY with pics, you can find it in the DIY links. It isn't a hard process if you have the right tools and some time. One suggestion is there is a guy in olathe kansas named Dennis Fickins that rebuilds these for 10 or 20 bucks a cylinder. He is on here sometime so he may see your post and respond. The only downside is having your ride torn apart for a couple of days. I got mine from phil on here for 110 each side shipped. Not a bad deal but in the future if a cylinder goes out I will Send them to Dennis. He rebuilds all of them not just the front.
