"I was very impressed with your Customer Service. The replacement switch was in stock and immediately shipped out to me. I gave the switch to my local auto repair facility.(Arts Automotive Service in Longview, WA.) They had trouble locating a new switch. After telling them about APW, they are going to contact your company and see about purchasing parts from APW for their business." posted by: Silverfox on December 29, 2014
