I would like to commend Josh Stabler of Shadow Tech (Hog Saddle) for his excellent customer service. I emailed him that I had lost the bolt and spring for my unit. It did not malfunction or break, I lost it. Entirely my fault. He emailed back and asked for my address, then 3 days later I received the parts in the mail. You cannot ask for a better commitment to a customer than this, and I applaud his ethics.
