Searching around here I've found info that indicates that '67/'68 tilt-wheel Cadillacs and tilt-equipped Oldsmobiles shared turn signal switches. Does this include the cam or is it just the electrical switch that's interchangeable? I found a '67/'68 Cadillac tilt wheel turn signal cam for $30 but can't find any solid confirmation that it drops right in. My switch works fine, but it's never held in either direction.

Here is the part in question.
