    '68-'69 Hardtop Protective Tips

    The '68-'69 TIM states that the bright protective tips were added during December 1968. I have the Chevrolet Dealer Service Technical Bulletin dated July 12, 1968 which describes the damage on early '68 models and the part numbers to add the tips. The bulletin clearly states that the tips will be used in production (concerning 1968 Corvettes). As the date is July 12, late '68 cars and ALL '69 cars could (should) have the tips. I owned a late '68 Bowtie/Duntov car which had the tips. My early '69 car (November 1968) has the tips. I believe the TIM should be updated to reflect this.

      Re: '68-'69 Hardtop Protective Tips

      Hello Dick! After I posted, I dug out the '68 and '69 AIMs, and now I understand the date of December '68 in the TIM. That is definitely the date the parts and notes were added to the AIM. This explains the info in the TIM, but where does this early service bulletin put us? Does it imply that procedures at St. Louis were in place even though the AIM was not yet updated? Or, does the AIM date make precedence over the bulletin? I know we have had these types of conversations here before, and I can't recall what some of the guys have told us in the past regarding items like this.

        Everett, there is a survey forthcoming. It is an update of the original 68-69 survey conducted by Mike and Cathy Johnson in the early/mid 1990's. The tip question is one that is on the survey. We are hoping that with the advent of the Discussion Board, that more people will see the mention of it and will participate in it. We just missed the deadline to have it included in the forthcoming issue of the Driveline, but it will be in the next.

        To have your name on the list to receive an electronic copy of the survey, sent an email with you email address to ncrs6869survey@aol.com

          AIM vs Service Bulletins - John H., Art A., Terry?

          Thanks Dick. I will sign up for the survey. Regarding implementation of items in service bulletins dated in advance of actual updates to the AIM - can anyone shed some light on this? Perhaps you plant guys?

            Everett,

            The July 68 Bowtie L89 you owned may have been one of the first to get the tips and they were actually painted if you remember. The judges had real heartburn over them when it was judged more so in flight than Bowtie, I think the Bowtie judges realized what they were looking at and the Flight judges couldn't sdee past the manual.

              Everett -

              The A.I.M. change dates in the revision block aren't a very accurate depiction of the date a change was actually incorporated in production; they just indicate the date the sheet was revised and re-issued by Chevrolet Engineering Graphics. The actual incorporation dates were handled through the NPC (Notice of Production Change) system between the plant, Engineering, and Production Planning, depending on whether existing stock was to be exhausted or scrapped, and those internal documents were never published outside of GM. This is another area where observation of known-original cars is a more accurate indication of when a change actually took place.

              I wrote an article on this subject entitled "When Did That Change Shown In The A.I.M. REALLY Happen?" in the Summer, 2001 issue of the "Restorer".

                Yes Roy, you and I know the car well, and know those tips were original! This should be one of our best data points in a survey!

                  I recall your article John. I agree that observation of known cars is one of our best tools. We use the AIM when it is all we have, and we need to use any factory documents when we have them, to build our cases. This service bulletin, along with some known real cars may make the case that the date for these tips was earlier than the update date for the AIM.
