47-55.1 '54 front tire/wheel situation

[mike.v]

I just bought a '54 GMC step side short box sitting a '69 C10 frame. As you can see in the picture, the front wheels sit almost flush with the outside edge of the front fender. The wheels are 15" x 6" with a 2 3/4" setback from the outside edge of the rim to the mounting surface of the lug nuts. I would like to put taller tires on that would stick up into the wheel wheels. I see 2 possible solutions. Have wheels made with more offset to the inside (probably an additional 2", which I don't know if that's doable or not. That would mean a wheel with only about 3/4" offset to the outside. The other would be to get some shorter A arms that would pull the wheel in (see pic). It looks like (if they are available) I could move in about 2". Anyone have any suggestions on these ideas or some other option?
