Getting back on track, the op is asking about 15x4 wide and 4” bolt circle..!! I too would like to know if any of these can be had.The only thing I know of in the past were custom units..Swingn’
I found some on Wheel Vintiques site. Very pricey but 15 x 4 wheel on a 5 x 4 bolt pattern. I have the same company steelies on the rear but 15 x 8 on a 5 x 4.5 pattern so it shouls look good with the poverty caps all around.
