will a 71 Polara fender fit a 70 Chrysler 300

I am new to the C bodies and what swaps between each other. Next week I am going to go look at some C bodies and the guy has some Polaras, etc. I need a passenger side fender, lower rear quarters and trunk drop offs. What models are able to swap back and forth. Also is the 71 Polara the same since it sounds like he has a couple of those?
