Will a 75 D100 turn signal switch work in a 71 Duster?

I'm looking to combine my order on rockauto to save on shipping but they don't carry a turn signal switch for a 71 Duster. They do once you hit 73 but that switch is definitely wired differently.

I recently did the turn signal switch in my 75 D100 with a switch I bought on rockauto and I'm comparing the pictures of that to the pictures of a NOS one on ebay and they pretty much look identical to me. Does anyone have any clue if they interchange? It's $45 cheaper than buying a standard 71 Duster switch on another site as well. What do you guys think?
