I'm slowing crawling along on my resto project, and am getting to the rockers now. I did a web search to see what's out there and found a piece for front outter cab floor and inner rocker panels at J.C. Whitney. This costs more than the outer rocker panel. I don't need any of the cab floor. But, the inner and outter rockers are rotted away. Has anyone used these pieces? I wonder why they cost more than the outter rockers. Any comments or suggestions would be appriciated.
