your rocker looks just like the one I put on my suburban.

it did not fit very well either, I got the door lined up, and then gapped the rocker to the door, in my pics you can see where I put the spots, which were close to the factory spots
the bottom did not line up with the inner either, I just ended up running beads, instead of spotting to the inner.
I also hung the fender too, and lined it up with the door , just to be sure that the front of the rocker lined up.
