Erick,

Glad to see you on the forum.

3) It could be as simple as adjusting the level control valve or as expensive as needing new hydraulic parts. You'll need to follow the prescribed diagnostic steps on this one.

5) Many folks say it's easy to repair broken springs. I've never done it. Consider replacing the seat bottom. I believe the newer seat design in common between 83-85 sedans and wagons. I'm sure someone can verify. It might be possible to use a seat bottom from a coupe or from a 77-82 sedan or wagon. It's easy to take these seats apart.
