Mike, I am pretty sure mine are the same as Jason's. It seems like I looked at the vanes before I installed them and they were straight. I work about 50 miles from home so it'll be later this evening before I can look at mine.
As I said in my PM, it really makes perfect since that these would have a break in period and I will let you know as soon as I get passed 600 miles or so, or they get quiet, which ever comes first. LOL!
Again Mike, Thanks for your diligence in this matter. It has been a pleasure dealing with you and TPS. While I'm thinking about it, I may owe you an itrader rating. I'll take care of this for you, I totally forgot.
Thanks,
Kyle
