1966 Chrysler 300 questions

Hello
I am gearing up to buy a 66 300 coupe and I'm new to the world of c-bodies. I was always an a-body guy (Darts, Valiants, Early Cudas I've owned a few of each) and had dreams of big block b-bodies... but age set me straight a bit. At almost 30, I'm coming to appreciate the cruiser. Good power. Comfortable seats. Reliable standard equipment I didn't buy excitedly at a swap meet, throw on the car, only to have it destroy more than itself... (wasn't me. I just warned the guy and watched the aftermath.)

But after years of getting AMAZING advice from some of the most knowledgeable mopar heads around over on ForAbodiesonly, I'm here to join you guys with the land yachts. Hope you'll have me.

First question I have is, I have a dented passenger fender. It's repairable, but I also purchased a same color donor 66 parts car. (That car was dismantled prior to me)

Will the front fenders of a 66 4-door 300 fit a same year coupe?
Size, fit, AND steel thickness? (Nothing worse than the look of different thickness panels)

THANK YOU for your time guys.
Young guys like me would be lost without your expertise.
