I found the parts diagram for the 35plus21lc and it shows the 07010 pn for that motor so it appears I was misinformed and now I have a old rod in my motor which is weaker but lighter.I just talked to them again and the guy said he just talked to jim and said that he was incorrect.He said that the new rod is more expensive and that they didn't see any reason for having both rods instock and that they were trying to save us some bucks.My reply was that I ordered these 07010 rods because he told me these were the new updated rods.I also explained to him that I would like to return them to him because if novarossi made a more expensive rod for the motor that they did it for a good reason knowing that it would be harder to sell a more expensive rod for the motor.He said that he wouldn't take the rod that is out of it's package but for me to send the other two back to him and he would "see what he could do".
