Brad-After completing a 1 1/2 year frame off restoration on my 56, and Chevy Duty being my main supplier (literally thousands of dollars spent with them), I did not experience any of the problems you did. I,also, had to return a few items that for whatever reason, would not work on my truck, but always was treated with respect and given class A customer service. I often spoke with Angie (Extension 245) at Chevy Duty, and she was extremely helpful and courtious. If you are treated rudely, you should call back and ask to speak with a supervisor to resolve the problem--right then! There are too many parts suppliers out there to treat their customers in the manner you describe.
