how much does the aftermarket outer rocker cover? my inner rocker looks good but the rocker is rusty under the sill plate where frt body post attaches. hate to buy the complete rocker and cut it all up. havent been able to find any pics yet,

I bought a replacement rocker panel 6 years ago and unless they have up graded their tooling it was useless. I had a bashed section of rocker to replace. I cut out the bad and tried fitting the new piece in. The profile was off 1/2" on some of the bends. Had to find a used rocker, (off a 65 GTO), and it fit in perfect!!! I suggest the same for you or use sheet metal since it is covered up.
