Don...I've got a RAM mount that I used on the '06 to shoot just to the outside right edge of the windshield on my '06 SEUC with a video camera. I think it might even be for 1 1/4" bars (U-bolt with shrink tubing on it). It has the 5-6" arm and also has a quick mount plate to take the camera off when you stop and go inside somewhere. That is...if the GoPro has the standard 1/4" -24 female tripod mount on the bottom of the case. The U-bolt will mount practically anywhere, and I might even have a 1" version as well. All that stuff is in a box in the garage, so I'd have to look to be sure. Let me know...
I have never cared for the way the RAM mounts LOOK, but they are functional.
If you're interested, I can take a photo of it and send it to you.
