Can anyone send me blueprints for any tube-chis open- wheeled race car?

Does anyone have a set of blueprints with dimensions for the tubes and roll cage and everything? My uncle, dad and I are wanting to build an open-wheeled racer but don't know where to start. We have access to many types of steel tubing and stuff like that, all we need is some numbers to get us started. Any type of old Indy Cars, Formula 1, Formula 2, Formula 3, Formula Vee, Formula Atlantic, Formula Ford, any of Lotus's Formula 1 or Indy Cars. Or ANYTHING else similar to this would be helpful. Thank you very much!
