Parts: How much are they worth?

[Dana Loomis <dloomis@domain.elided>]

I need to find out the fair market value of some used parts for 105/115 Alfas:

- -Complete airbox and intake manifold setup for a twin-carb Euro car
- -Dell'Orto 40DCOE carbs
- -Marelli Plex ignition (complete)

These items are in decent, used condition and would be offered by a private
seller  with no guarantee.  Anyone who can provide some guidance, please
post to the digest or reply to me offline.  

Thanks,
Dana
