Yes, they're decent. They clip into brackets in between the roll bars. The wind deflectors often come up on eBay, unfortunately often without the brackets. I have seen people have made the perspex ones and made the channels for them to slot into. I was talking with cj10jeeper about this at a recent meet and we didn't think it would be too hard to get two buy the channels that you would use for a perspex unit and adapt them for an OEM deflector.
