1969 dodge dart rear rim size

I got them here:

American Racing Custom Hot Rod Wheels

And they are these:

American Racing Torq Thrust SL

What I don't like is the valve stem is on the inside of the wheel.
Did you try anything with a 0 offset or 4.5 backspace? Or do you think it would clear the quarter panel? I found some wheels, 17x8 with 4.5 backspace(0 offset) and want to run a 245 tire. Questioning whether or not it would fit. It’s driving me nuts since I’ve already spent money on wheels that didn’t fit.
