ROSTRA
OEM-style Engagement Switch
APPLICATION GUIDE

      Rostra manufactured OEM-Style Engagement Switches for most domestic vehicles from 1965 through the 90's. They continue to provide OEM-style switches for several applications, such as the General Motors multi-function switch. Unfortunately, many styles are no longer made by the factory, however we still have most parts in stock.
      Makes or models not listed here may use one of the many Universal Switches available from Rostra.
