I have looked into changing my seats out as well, and here is what I ahve learned:
First the easy part, you can use the seat adapters for a Chevrolet Colorado/GMC Canyon, they are the same mounting as our H3 seats. Dont let the company tell you otherwise, I know for sure they will work, its the same part number.
The hard part:
You will need to transfer the passenger seat occupancy sensor from the factory seat to the new seat, or get a new sensor for your new seat. It is an air type bladder that detect the presence of a person sitting in the seat. Also, you will need to remove the seat position sensor from the old seat frame, and reuse it on the new frame, that means some cutting and welding/or bolting it on. It is a metal tab that has a sensor mounted to the track, and it detects where your seat is located in relation to the airbag so the pesky computers know when/and how fast to deploy the airbag in the event of a crash.
While it is not totally impossible to make aftermarket seats work, it is a pain. I looked at those exact Corbeau seats, and the dimentions are close enough to the factory seats that I dont think they would look out of place at all.
Hope this helps.
