A buddy of mine just bought an 89 Ford Ranger with a Meyer ST-72 plow and a U-13 pump. The equipment was mounted to the truck already, but no controls or cables. He went to get parts and said the guy laughed at him and told hime that stuff was over 30 years old (said he couldn't get parts). We bought some universal cables and custom made the control setup. It all works now, but how old is this stuff?
