the intake manifold is worth about 100$. If the motor is in good shape, you can probably sell it complete for 500-1000$ depending on mileage.
auto trannies are pretty much useless.
Headlights (if ellipsoids) are worth 75-250$ depending on condition.
Non-rusted out panels might be worth something too. Taillights, mabye, i dont see those breaking often.
