I had a pair of seats out of a 90's Mustang I was going to use. They were in really good shape, and comfy, right color, etc. I got the passenger seat installed and lived with it for a while. I ended pulling it because they just did not "fit" with the interior. The seat bottom was a bit wider and crowded the console, and the seat just generally looked out of place. Back to an old adage "Just because it fits doesn't mean it is right". Those seats look to be sized correctly and really look good with the interior. I looked them up and they are pricey, but Corbeau is a good seat, so I am sure they are worth it in the long run. Do you know, are they a "suspension" style seat?
Also, another question...the window switches in the console for your rear windows, is that the factory location? I have swapped out the original rear console in mine for the piece from my parts rig because it had the cup holders. Now my rear window switches are just hanging out under the brake handle, and I am trying to figure out what I want to do with them. I like the way the location in yours looks.
