Just wanted to thank Adam publicly. Ordered headgaskets and studs this past Friday night. He's going on vacation this week, and my truck falls on the borderline of the build date for the 18mm or 20mm dowels. He ships the headgaskets for me on a Saturday with a drop ship for the studs, and he sends me both sets of headgaskets just to make sure I have the right ones to ensure a quick turnaround! That is great customer service!
