I am looking to replace the turn signal switch and cancelling cam in my 64 cutlass. Through the usual vendors they list them for 64-66 GM but say they wont work for the cutlass, but list them for a 65 cutlass. Does anyone know what is different on the 64 that I can not find the switch for? Or does anyone have a source for one? Thank you in advance!

 

There are 2 different ones for 64 - 66. There is a plastic one and a metal one. You have to replace with what one is in the column.
