Dear Mr. Willis: Thank you for your letter of July 11, 1967, regarding the applicabilit of the Federal Motor Vehicle Safety Standards to accessories which are purchased for installation after procurement of the car, and in particular, Safety Standard No. 201.; Standard No. 201, 'Occupant Protection in Interior Impact -- Passenge Cars,' applies only to vehicles as originally equipped and does not apply to accessories such as 'after market' auto air conditioners. However, the public would certainly benefit from the maximum degree of conformance that may be feasible on after market installations.; It is sincerely regretted that a written response to your first reques was not received by you and trust that you were not inconvenienced.; Sincerely yours, George C. Nield, Acting Director, Motor Vehicle Safet Performance Service;
