My third seats were in very poor mechanical shape (bent parts, missing parts, etc.). I decided to fix it and for that I purchased used seats from ebay. Got the seats but they are a different tone, so I figured I would change just the mechanical parts of one seat and place them in mine. Well, turns out is an impossible task. I first unscrewed the plastic cap covering the mechanical part, that was somewhat easy (had to pull hard on the shock it has but made it). Then unscrewed the arm that connects it to the two clamps that lock the seat to the floor. Then there is this "ball and joint" connecting the shock to the seat I just could not take off. However that is not the sad part, the sad part was realizing that once I undo that, there aren´t any other screws or pieces to be removed to be able to change the whole mechanisms underneath. Has anyone tried this task and succeeded?
