Not technically boatsided, but the same basic idea. Keep in mind that if you want to truly raise the rockers up far enough to require boatsiding than you will have to modify the lower door hinge (assuming you are keeping doors) and will then start having issues with keep the window mechanism functioning.
I cut out the stock rockers and lower sheetmetal along the front and rear fenders up to the bottom of the stock lower hinge, and then grafted in 3x3 tubing. For perspective of how much higher the new rocker is, there is almost 5" cut out of the bottom of the doors. I also replaced the floors with flat 1/8" plate at the same time, and with the floor basically at the same height as stock there is about 1/2" lip where it meets the new 3x3 rocker sits higher.
