Thanks everyone for all the great feedback. Fortunately I discovered that when I mounted my cab, I had added 1/2" to much between the cab and the frame. After removing the extra rubber spacer also lowered the rad bracket to front frame 1/2". Now the side view between top of the running boards and bottom of the cab looks even. I did a dry fit with the new cab to running board rubber seal and it looks to be just about perfect. I'm happy!
