Dear Mr. Kamath:This is in reply to your letter of August 6, 1973, i which you inquire whether incomplete vehicles manufactured before the effective date of Motor Vehicle Safety Standard No. 121, 'Air Brake Systems,' (September 1, 1974) must conform to the standard. You ask further whether complete vehicles manufactured from these incomplete vehicles must conform if they are completed after the effective date of the standard.; Incomplete vehicles manufactured before the effective date of Moto Vehicle Safety Standard No. 121 need not conform to that standard, and complete vehicles manufactured from those incomplete vehicles also need not conform to the standard.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
