Ok, well instead of purchasing the $260 fwd adjustable cam gears for my hybrid project, I bought ones from a 95' nissan pathfinder 3.0l @ $30 a piece my cost from the dealer I work at. They are square tooth, so if you want a round tooth design, I was told 94' Nissan maxima 3.0 cam gears are round tooth. I'll post pics as I modify them.
