    according to this:
    http://nastyz28.com/camaro/camaro70.html
    it was 4136. Numbering started at 500000. There were even a few "walk thru's" pushed down the line in December and I think those got numbers starting at 500001.

    I looked and you were right about the number. I cannot understand because that L-78 had the Vin stamped on both the pad below the oil filter and it was on the side of the muncie 4 speed M-21 transmission (passenger side) and most parts date codes were within a week. I bought the L-78 at the end of 1988 and I doubt very much if guys were making fake cowl tags and stampings way back then.

    John, The VIN number is an "issued" number that includes production from both the Van Nuys plant and Norwood plants. The sequential build number is on the trim tag.

    That makes sense. If you add up the two totals (Norwood and Van nuys) for January than my previous L-78 is correct.
    Thanks John.

    My O5D Norwood built Z28 has a engine casting date of D280 (April 28, 1970).
