Just posting to say THANKS to Dane at Mad Jack Racing and recognize him for excellent customer service and pricing. I ordered his Duramax filter kit last week and it was here by Friday - from SoCal to AL in just a couple of days. He quickly replied to my questions via Private Message on the forum. The pricing was a good deal, and the service was top notch. It deserved a mention - I've also dealt with Husker Diesel and Chris Kelly ("bigdaddydiesel") and all the supporting vendors that I've dealt with here have provided great service and patiently answered my questions.
