Update:
I googled around some more and came up with this.
http://www.finishlinewheels.com/HONDA/PRELUDE/1994/
They look like the rims in the pic I took at the dealership, and the listing says they are OEM? But for what model Prelude were they stock? They show up under '93 '94 '95 '96, but I have never seen them before now.
Still looking for the best price on them. This site is 125 bucks a pop.
