8K VINTAGE AUTOMETER  TACH                                                               

   3 3/8th's wide the outside edge to edge on the chrome is just under 3 1/2 inches.  

   TESTED  0N MY BENCH TESTER WORKS GREAT!!!!!!!

   THIS IS A SIMPLE 2 WIRE HOOK UP  SIGNAL FROM POS SIDE OF DISTRIBUTOR AND A GOOD GROUND. 

             THIS WILL REQUIRE A SENDING UNIT  (I DO NOT HAVE ONE) 

                   TACHOMETER IS DEFINATELY PRICED ACCORDINGLY. 

  I WAS ABLE TO TEST IT ON MY BENCH TESTER TACHOMETER WORKS PERFECTLY.
