The big hole in the drivers side rocker is for the e-brake shaft. You can put bolts in the small holes to pinch the rocker,floorpan lip and inner to outer cowl together for fit up. The right side rocker has the holes but they do nothing. Must just be easier to stamp a mirror image. I don't know if the original rocker had holes on the right side...mine was rotted away as well. Personally I thought the outer cowl was one pc. that was best to drill out all the spotwelds and replace the entire panel but each situation is different. Good luck and be patient.
