I have a 67 skylark and am replacing the signal switch in the column. I have ordered the switch that is supposed to be the rignt one but it does not fit. It is too tight to fit in the cup. Do I have the wrong one? I read where some are red and some are white. Mine had the white one and thats what I replaced it with. Does the cup need removed to install? It is a tilt wheel also. I was thinking about just getting a new column from Ididit but appears they dont make one for the Skylark, only the chevelle.
