If you have the means, I think the one-piece rocker would be a good idea. Are you planning on going a gauge thicker than stock, or thicker than reproduction? Are you going to carry the B-pillar down to the bottom of the rocker? Also, you have obviously noticed how the B-pillar is open to the elements from the drain in the inner rocker. I would love to see what you are doing with the rust preventative and sealing this off.
