Ebay is the place for a tach. The prices are the best. Gas engine tachs are easy to connect to the distribitor. Diesel powered vehicles having a tach need a magnetic pickup to work. Diesel pickups for a tach can be triggered by the flywheel, harmonic balancer or any part that turns at engine speed. Some clever folks have made a tach pickup by glueing a couple magnets to the power steering pulley. Frank
