I noticed when I was first driving my car the drivers seat seemd like it sat up a little higher in the back then any of my previous 1st gen cars. so I nosed around and found it had some kind of seat extensions installed. I dont think they are original since there are no part numbers on them. they are well made and look like they have been in the car for years. here are some pics, any advise on if they were maybe a dealer install or aftermarket?
