Don't know if this will help, but go to: http://www.acmeair.com/history.htm "Then in 1991, Acme purchased the majority of assets of A.R.A. Manufacturing Companys Automotive Air Conditioning Division, including the product line and new state of the art engineering department. As a result, Acme Manufacturing Division began producing high quality after-market dash air conditioning systems." google is great! Best Wishes, Joe M.
