Your guess is as good as mine. I need a set for my Cuda. I see them listed for $269 from a couple places and other places want over $100 more for them. Kinda makes me leary to trust the cheaper ones, or is the more expensive place just that, an expensive outfit? Hard to decide since I've never bought any. If you find good ones at a good price let us all know.
Unless you're doing a factory restoration consider making a set. They are simple.
I have a friend with a long arm quilting machine who will sew a set for me but it can be done without that.
