[SparkCV]

Same happened to us last year. We were able to find replacements. I think I ordered from Amazon. The color wasn't exact to the originals. I believe the middle hole did not line up correctly so had to drill a new one. Also removed the arms from the fan and bent slightly up to increase clearance above the slide. Replacements and slight adjustment have worked well. A solid 1 inch clearance now on all blades.
