History When did Fenton Hustlers first hit the market?

I see a bunch of Hustler II's and III's from the late 60s and early 70s but I ran across a set of Original Hustler wheels and can not find a date. Was wondering when they first started hitting the market (The Original first Edition of them)

Sometime in the mid 60's I think. Around 1965 the aftermarket wheel thing really took off and I am thinking some local guys had them then. They seemed to be the first thing done to 66 Chevelles or quite similar wheels around this area.
