If it is anything like our 1987 you will have to drill out the rivets and remove the inside door skin in order to replace the blind.
Or you can do like we did...I pulled the blind out as much as I could and then used a razor knife to cut the blind off the roller. Then measured and purchased a spring loaded curtain rod and a cheap curtain. This method is a lot easier than removing the interior door skin.
