Those are not 1971 Duster . These are and they are quite expensive. I have a large box of them but I didn't go through all of them yet. I have two cars I need 4 to install. I have to make sure they all work. They get pretty corroded over the years. I need to put some good pairs together. The fender takes three holes to install on 71 cars. I have seen them for sale at times and usually buy them if the price is right. Its the bulb sockets that go bad. So having spares is a good thing. If you buy used make sure they work. I didn't see any in the parts I just brought home .
I just went through markers for my car and was doing the signals next. I will keep you in mind after I see what I have. Out of all of the markers I got 6 good sockets

They never made chrome for 71 plymouths they were all painted. If you have time to wait I will be getting them out i'll need a set for my brown Duster soon. I probably won't be putting a set on the other Duster. My son reminded me I bought Fiberglass fenders and doors. and my 71 Demon's are chrome smaller sets.Thanks Oldmanmopar
Someone put a set of 73,74 style on my 71 Duster. Car is getting restored and would like to have the right ones to put on when I get to that point. Chrome doesn't matter as I plan to paint them black.
