I have 02E LOS z28 with the correct alternator.I had it rebuilt back probably 15 years ago. I seen this post so I checked the back of mine. It was rebuilt and a 1969 rear half was puy on during the process. I doubt that many years ago it was done to screw me but anyhow it was done that way. I am glad the correct original front section with correct numbers was not misplaced.
