I couldn't find much on this subject in the archives, so I thought I'd ask the membership. In the 17 years that I have owned this truck, this is the only dash component that I haven't replaced or removed. It's the long handle switch right above the 3-lever light switch. Is there anything I need to pay special attention to? and is MS39060-2 the correct replacement part number. The truck is a 1971 AM General..........Thanks.
