Dear Mr. Martin: This is in response to your November 2, 1976, letter concerning th type of statement regarding Federal Motor Vehicle Safety Standard No. 301-75, *Fuel System Integrity*, that must be included in the incomplete vehicle document supplied by General Motors Corporation along with its Cadillac commercial chassis.; You have essentially repeated the argument of your August 24, 1976 letter to me, in which you disagreed with the interpretation of 49 CFR Part 568, *Vehicles Manufactured in Two or More Stages*, that appeared in my July 20, 1976, letter to you. My letter explained that Part 568 prohibits the use by General Motors of a 'type (iii)' statement with respect to Standard No. 301-75 in the 1977 Cadillac incomplete vehicle document.; Both of your letters emphasize the significant effects that the work o the final-stage manufacturer has on the capability of the completed vehicle to conform to Standard No. 301-75. The NHTSA is mindful of the significance of these effects, and has never suggested that the final-stage manufacturer's work would *not* substantially determine the vehicle's conformity with the standard. Both of your letters erroneously conclude, however, that because the work of the final-stage manufacturer '*will* substantially determine such conformity' (your emphasis), 'the design of such an incomplete vehicle many times *will not substantially determine* conformity...' (your emphasis). This conclusion ignores the interpretation in our letter that, with regard to the vehicles in question, conformity is '*substantially determined by both* the design of the incomplete vehicle and the manner of completion by the final stage manufacturer' (emphasis added). The NHTSA stands by this position.; As you have requested, the letters discussed above have been include in Docket No. EX76-3, Notice 2.; Sincerely, Frank A. Berndt, Acting Chief Counsel
