Here is a pic of a mid 70's Chrysler 15" x 6" aluminum wheel that I reversed ,literally. The side you are looking at used to be the back side of the wheel. I liked the look of the ribs on the back side of the wheel, they reminded me of some vintage Halibrands I saw a long time ago. They are going on the back of my '27 Track T. I welded up the holes that attach the original hub cap to the wheel, and faced it off in my lathe. I blasted the center, and satin finished the rim portion, although I am going to either paint or tint the wheels to have the gold color of old magnesium wheels.
