Need help with wheel size for a '66 C10

[1964c20]

I'm sure this question has been asked on here many, many times before, but I'm still confused so I'm gonna open up the conversation one more time. I have a 1966 C10 that has 2.5 inch drop spindles on the front and 4 inch drop springs on the back. I'm looking at wheels for it and I'm not sure what will fit. I want the wheel wells filled up as much as possible without ANY rubbing. I picked out wheels that I like and they come in a 17x8 size. I have no idea if these will work on there or not. Any help or guidance would be greatly appreciated. Thanks and sorry for beating a dead horse!
