ClubGP would be my best bet. They came on the 2000 Daytona edition GTP (I owned one) and I think the 40th anniversary models 2002 I think.

They came on 40th Anniversary GP's and Daytona Edition GP's. 2 years only, on limited production cars and they aren't being made. I paid $200 Canadian. You really gotta put your nose to the ground, but I put out "feelers" on a few GP boards and got a bite, locally, after about a month
