Howdy everyone, just starting the side skirts for my slider 7 and was wondering about the C-660. i can't find them but I do have two pieces of AS3-032x4 9/16x32. I assume they need to be fabricated but wanted to ask before I start drilling.
The two sheets AS3-032x4 9/16x32' are the correct parts that you need. This was the only identification that was on my parts and that is the part number that Van's lists them under on their web store.
Remember to remove the half inch of material at the bottom front of the skirt as this will provide clearance to the fuselage when you slide the canopy back.
