I just got a 99 spec replica wing from Ebay. I am really happy with it. Test fitted it today and it looks real nice. What do people use between the spoiler and the car? Two-Sided tape? When i took the old R1 spoiler off it had adhesive tape on it. Thanks. This is the wing i got.

Mine is fiberglass and it came with a foam gasket which covers the entire bottom of the wing. I suppose if you got some heavy duty double sided tape and made sure you aligned the spoiler properly before setting it down, then that should work as a gasket. Just make sure you don't move the spoiler once it's placed.
