Turn Signal Switch for '70 Challenger

[joppe]

hi, I read this post while searching the net. i bought the turn signal switch said to fit my 1970 challenger, but just as noted here the hazard switch was too wide. i grinded it but connecting the switch nothing works; my rear turn signal lights flash at the same time, when turning on the power and give a turn signal only the rear light works, and on the wrong side. the only thing that seems to work is the hazard, then both front and rear blinks, as well as the instrumentation bulbs.

my question is hence; is the size of the hazard light switch knob the only thing that differs the years?
is my new one simply a result of poor labour, i.e. faulty, wrong connected or such? my new one looks like very cheap compaired to the original, and it is bought from the states and is said to be "authentic mopar"

thanks in advance, Johan
