I bought some from Dennis a year or so ago, and no excuses, they fit like a glove. Priced right too. Unfortunately, very difficult to get them from PPC now. In addition, I've swapped stock arms from car to car, no problem. To say they can't be reproduced with accuracy is just not what I've experienced.
In any case, this isn't the first time that poor communication has soured a customer. Although I appreciate your explanations, it would have been better to have gotten them from the Vendor. I won't be re-ordering them that's for sure.
