The screw for this cover would not screw in. I had some other screws with the same thread pitch and chrome that I had to substitute. When you buy Joker Machine if you don't have hardware on hand plan a trip to the hardware store. This is the second Joker Machine part I had this problem with. Using junk hardware is a bad reflection on an otherwise well made part.
I wasn't that impressed with this, it felt light and not very sturdy, and the contrast chrome didn't look as well as the Roland Sands parts I bought to match. But I am keeping it because there really weren't that many choices for an air cleaner insert.
