4.5 puts it way too far out and into the fender lip, and if 5 inch is a tad too much, I can always run a thin spacer to move it out a touch. My measurements puts the tire at least 9/16ths away from the leaf spring, which should be enough.
Just ordered the wheels from Wheels Vintique, now the waiting part. Tires are 275/50-15 Nittos.
