My 72 swinger with 265/50/15 rubbed before my front sway bar. I have a 3/4 offset mount and shackle kit too.
Enough squat or body lean, and my tires still rub just slightly.Where do they rub im looking at running the same size only 4.5 backspace
Rear rims are 15x8 with 4.25 backspace on an a body 8.25" with drums (56.75 wms to wms).
