Sorry about the angle. I grabbed a quick side view while being in the trash can. Just wanted to show you that the rear wheel and tire tucked up nicely in to the wheel well. No rubbing and no lip rolling required.
Here’s my 68 with 17’s but a 4.75" back space. I went with a taller 50 series tire however. I have seen evidence of a slight rub after driving around this season. Will update my post eventual.
