I phoned them Friday afternoon and they are sending out the new spline adapter but it's on back order so not sure how long I will have to wait.That sucks. I would be mad to. Call them on monday. I bet they get it right out to you. Just sucks waiting for crap that should have been there the first time.
I have been thinking about getting one those. Maybe the dished one so it moves the wheel closer. I also like the padded wheel.
