I'm hoping someone can share either the MoPar or NaPa parts number for the turnsignal switch that fits the 1968 Imperial non-tilt steering column. Also, I understand that the original, metal, airfoil-style wiper arms used in 1967 and 1968 may still be available. My search of the NaPa and Anco catalogs hasn't turned up a useful part number. Anyone know the right numbers? Many thanks. Happy New Year, Dave Duricy 1973 Imperial LeBaron 1968 Imperial Crown (conv.)
