I don't think the rear window visor comes in an in-channel version. For the side windows, there are, like others have said, in channel and ones that stick on with 3M tape. I have the in channel types for about 2 years and they've held up just fine, no problems. However, my rear window visor is stuck on with tape. I don't believe you can have a rear window visor that goes inside the channel because the sliding window would just keep going down because it has interference.
