When Slingmod put the Gap Fillers on sale I ordered a set and they come within a few days. I watched their video and it's not rocket science, but did take longer than expected to get fitted; existing Polaris panel are not all that precise. If you've never worked with fiber glass products before, and I had not, then I'd suggest wearing gloves of some kind or you will get bits of the glass in your hands. LOL. The products are well made; much thicker and substantial than I expected. I did add an extra screw to the lower inside corners and also attached the upper outside corners to the bracket provided instead of relying on the double sided tape which did not adhere well to the fiber glass.
Also added a new shift knob and boot from Slingmod while they have the 10% discount.
