Wheel and tire question for 68 GTS

i am in the same boat with mine, and I also am going for the white steelie look and poverty caps. Don't know what the previous owner was thinking...if you look at my set up-the front tires are taller than the rears. It has Wilwood manual discs up front I believe from a 73 (has LBP axles)
I am going with 215 65 or 215 70 fronts on a 15 x6.5 rim and 275 60 on 15x8 rear.
