17x8 Mustang Wheels on 64 Valiant Questions

Out in the garage with a measuring tape I found that with a 1" spacer in the rear with the rear end the car currently has will be pretty close to where the wheels sit now. Of course for some reason the drivers side sits out further towards the wheel well by almost half an inch for some weird reason. Perhaps once I put the 8.25 in and then measure it again I can get by with less of a spacer. Heres the 1" spacers Im considering if the rear ends are the same from drum to drum:

In the pictures, the rear wheels are against the studs (7/8" long) and the fronts are all wacky because the suspension isn't settled (being on a jack) and sitting against the 7/8" long studs)And yes, theres a chunk missing from one of the wheels but it still seals. I'm now curious if a 245/45r17 will even fit up front without fender clearance issues or rubbing on turns with the steering wheel locked one way or another.
