You can find the sticker referenced in the new NCRS 1968-1969 Tech Info and Judging Guide about 20 sheets from the back (its not numbered). The reference is in that Feb 1968 Chevrolet Service News, Pages 5 and 7. the title of the article is Tune-up Specification Change. I looked in Dobbins and 69 Bizzoco. I could have missed something, I did see the SB emmision sticker he used for a example, no help. I put a post here and NCRS. I left EMails with all the 68 BB A/C owners I could find in the Corvette registry. The AIM page 0, B1 does list the sticker as item # 6, 3927740 (a charted part) on the radiator and then moving it to the firewall position on on Jan 16 1968. As a charted part, that could be where our answer is, I don't have that chart referenced either. I can place the location change date by an orgional GM AIM I have. It has more data than the reproduction AIMs on the market. It has some neat info., sometimes. I also talked to Dave @ Jim Osburn Productions, no luck, and to Chevrolet and the Corvette Mueium, no luck there either.
Thanks for your help
