Recently sold my Duster and will be listing spare parts I had for it.
2 OEM turn signal switches that are for 1971 and newer, but work fine in a 1970 car. The only difference is that the Hazzard switch operates when pulling out instead of pushing in. Had both of them in my car and they work fine.
Ignition switch was probably original. It worked fine, I just replaced it when I restored the column. $100 for all 3 items.
