[64Downunder]

Hey I'm Building a 64 fleet side and have a porter built rear for it and i was looking at the wheel well and my rear rims are bout 4" inside the guard which i was looking at getting different offset wheels ( they are 5.25" backspace foose )but the rear wheel well looks like it curves real far in and when having it sit so low "the ground" i don't see how i can get it and closer than where it is.
