C Body gas tanks

I have a 1966 Polara. I’ve found gas tanks for it on eBay. I’ve also found that Dorman makes a gas tank that says it fits a 1965 Polara. My question is, will that tank fit my car? I didn’t think there was much difference between the ‘65 and ‘66 Polara body wise. Thanks in advance for any assistance.
