Apex is right there arent many shells out there for the F201 since it hasnt been produced in a while. Locally some of the guys are running the same tires and wheels that we run in VTA.
E-mail d-drivesports english and ask them if they have anything for the F201. They are real good to point you in the right direction if they dont have what you need.
If that doesnt work get on the forum at
www.mlpmotorsports.net and beg Marty Petersen to pull you one or three. I know he is able and the shell looks nice even if its not a Tamiya mold. He has a nice history of mods and hop ups for the Tamiya F201. You should find some cool pics of his work while you are on his site.
