I was at the factory last weekend. They are moving most of the production to another facility so it was kind of hectic.
Mindi from Dollar was also there setting up her side of things. She told me that they will be handling most of the Sonic parts orders from now on. She was extremely nice and easy to get along with.
You may want to try getting in touch with her. She can probably help you with what you need, or get you the right person to talk to.
