Hey man, ... i was going to say ebay but i guess you know already .. but a good idea is to go cardomain.com and ask the prelude 5th gen owner that they have bought altezzas (beautiful and very unique altezzas) if they want to sell the OEM tailights ,
actually this girl she just got the fuggly altezzas last week! she's kinda my friend and here's her link:

.. i'm pretty sure that many people have them on theyr garages .. also for the other stuff who knows .. i mean, who doesn't like to make a extra$$$ specially when the extra $$$$ is in your garage??
Good luck man!
