Just a heads up about 6 volt flashers ,, buy up some extra nos ones if you can find them the replacement ones are electronic and do not work right just returned some to napa . Have not tried one of these taiwan flashers in any of KF"s but just installed one on a 54 Aero and yes the lights blink right and left but these things are silent and something with the way they are made the indicator on the dash does not light up . I much prefer having some indication the signals are working, i had one old stock flasher left i installed so all is good on the willys now . New updated parts are not always better.
