Well I'll tell ya

---I know the unit wasn't offered as of 7/69 because I would have gotten it instead of crusing the sreets with 456's and I was told there would be an Overdrive unit available later in the year--And to be honest, after the summer of '69 the unit went on the back burner Until I saw it offered by Motion in a mag early '70 ( Jan/Feb )---so given the time lag of putting the mag together-Motion could have been official offering units to the public by advertisement late '69 (Nov/Dec) ----So COPO your Camaro could have come with it late '69--Paperwork might be a little more reliable than my memory,but I'll stick with this version for now
