    That early tach takes a sending unit that goes between the distributor and the cap. That and the cable that hooks it up are hard to find. What do you want to run it on? I can supply you a picture of the parts you need if you want. Have a great day Gary

  5. Hi,
    I do the job for my winged Logo and curved glass 8k tach !
    Off the Crankshaft
    Using;
    Brand new Pegasus' Mechanical Tach drive 2:1 ratio + 12V SW electric sender (marine)
    I've tested it with a 12V battery and a measured Drill at 1450rpm
    Face dial indicates less than 1500rpm
    Then all of these parts works together !... ;)
