**NEW PRICES***
I've made some changes to the car (Van Diemen RF94) that won't be easily reversed, so the orphaned parts are for sale.
OEM Radiator ducts and floors, lower side panels L&R: $ see below
Zoomy sidepod air intake with plenum, like Reid's (retails for >$500 when available): $100
Photos to follow, but I'll warn you things are far from "as-new." They'll be great spares for you though, or a little work could make them beautiful again.
Prices are as asked plus whatever I have to spend to ship to you. That could be a bit for the side panels.
