Looking for wheels

I've never had any trouble with them either but always thought about adding the bigger brakes along with changing the bolt pattern as a bonus. I did some reading last nite and it looks like even if you find a donor car or use the 73 up stuff in pieces that you buy it puts the wheels out further on each side and I really don't want that. Idk I'm undecided on all of it st this point. I read the mustang rotor thread but that only gives you the 4.5 bc. The wheels I've narrowed down to offer the 4.0 bc so again really unsure what I'll end up doing. Thanks.
