SW Parts on Mockingbird in Dallas. You may have to pay the warranty replacement charge unless they cover it 100%. The only way to do it thru G Loomis/Shimano is on the internet and follow their warranty guidelines. They were VERY SLOW when I did it.
SW Parts is very slow on anything, They are horrible at customer Service. I went in the couple years ago, nobody was at the counter, I was only person there and then after a few minutes there were at least 5 people just standing in the store waiting for someone to come out and help them.
I avoid the place now
