Ive been to librarys and micofilmed many actual rare mopar selling dealers ad for every wingcar and other desirable cars.And sometime compared stock numbers from ad to car at shows Ive seen paperwork for. And found that actual car and gave the guy the ad for his car.But never saw one or found one for a 69 charger 500.Thats not that much on the 500-s outhere except for newsletter submitted material.And what turns up from time to .Ive looked in the 2 dodge charger dealer data books.Only seen in the one the charger 500 as only available with the hemi.but they came with 440s.So you cant trust all factory info
