Wheel Size Question.

Bringing back an old post. On the topic of 17s on a Barracuda, I'm interested in the 17" Coy or torque thrust wheels and am wondering what y'all think about 17X7 / 4.25 up front? is that enough backspacing or should something with at least 5" be better? Also im looking for a tire size that will clear stock fenders, what are you running? Im building a 67 notch back with disc brake conversion up front and an8.25 in the rear with stock leaf springs and drum brakes to be a reliable soon to be daily/weekend driver so Im not looking for anything crazy or complicated. I have scoured FABO with lots of differing opinion and looking to get a clear recipe for wheels and tires I can confidently purchase online and know I wont have any clearance issues. any and all input and pictures are appreciated. THANKS!
