Olds 403 code
I bought an Olds engine to rebuild, and I am trying to decode it. The pad under the big 4A on the drivers side is 29L157179. I know the 2 means it was put in a Pontiac, and the 9 is the year 1979, and the 157179 is vin # of car it came from, but what I don't know is what the L means. It is supposed to be where manufactured, but the choices I was able to find online were, M for Lansing, B for Baltimore, X for Kansas City, and Z for Freemont. What would L mean? Could it also mean Lansing? Would make more sense than using a M.
Thanks
