Verne,

Very interesting info...Thanks for sharing..That makes sense about the factory wanting to keep track of the body jigs used on various cars, to potentially show any problems. My green 1970 is a "pilot" car, but certainly not the first 1970 Chevelle built at Baltimore..It is perhaps the 1st LS6 built there(an extremely good possibilty), but not sure if that would have made them use "jig" "1" or not..I was speculating that the numbers might have had more to do with quality control (sort of what you are implying as well), but more for the RPO side of things..vs. the actual body assembly. Do you know why this practice only seems to have happened at Baltimore? Any thoughts on what appears to be some correlation between the "B D" codes in the data processing line..ie.."B D 0111" (my green car) and floor shift transmissions at the least?? I am working on trying to gather as many 1970 cowl tags from various Chevelles/Malibus (both "SS" and non-"SS" cars as well as floor and column shift) built at Baltimore. I'm hoping there is a direct relationship between the presence of a "B D," code and the fact a car is a floor shifted car or an "SS". This possibilty was presented by Kevin (musclecarkid on here) earlier. I'd love to chat someday..My work number is 800-669-5834 ext 238. thanks again for sharing some really neat info.
