Free or not. I can't say anything bad about Shimano. Anytime I've ever had a problem, their customer service has always been top notch. Quick to respond and very good about replacing faulty gear without question.
That Trevala rod is a very tough piece of equipment as well.
This setup will serve you well willy.
I snapped some pics of the washers and also with them mounted on the mainshaft. For whatever reason, my camera is acting screwy and won't let me upload the pics. I think you get the idea anyways.
