Many other members could give facts. Duane H , Jim Lore , Rich Johns all are far more knowlegable than I am and would have dates and facts. I know there is some reference materials out there that state GSX production ended in May '70, but there have been at least one or two documented June builds for a '70 GSX ... and one of them I thought was a 2nd week of June date ... possibly the last one. I have seen documents on a 2nd week of July '70 Skylark several years ago. Remember, there was a big strike at GM for the '71 model year, but I am not certain that the strike extended '70 production any.
