Well, go for the fresh air duct if it has one. Check the radio on the drivers side to see if it has a radio bracket. The passenger side A/C duct if it's in nice condition. Those go for about $100 new. The console if it doesn't have a lot of burns in it. I've seen the 403 Air cleaner housings go for quite a bit. The A/C brackets could come in handy. If it has a rear window defogger.....grab the timing circuit...and if power windows, the relay for that too. If it has the WS6 option...grab the power steering gear and rear sway bar. Then figure out what things you want on your car that that car has and pull those parts....like tilt column....power trunk release, map light, kick panel lights...etc.
The clear lens covering the lights.....that illuminate the plate....I think that would be part of the tail light assembly.
