You may also want to look at Autozone for clutches. I have changed out about 8 clutches over the years and only one had to be replaced again (my father in law's) and I always get the one with Lifetime warranties if it is only a little more because the only one I ever had that did wear out again was the one by my father in law. His second clutch had the Limited Lifetime warr. after that.
Autozone has good prices as well and can be bought online if a store is not near you.
PS. Nice looking truck concidering it is 11 years old. New paint job?
