Rocker panel replacement

Hey guys,
I have a rusty driver side rocker panel and need to replace it. Is there any after market to order a new one?
Or maybe a junk yard in the tn al ga
tri- state area. I'm near Chattanooga, tn. Thanks

 

I’ve been reading everything an available on rocker repair on this site and others. Post some pictures and be prepared for the answer to be cut it out and weld in a new one. $$$ if you pay a shop, or lots of time if you do yourself (so I’ve heard). My 2006 developed holes in the rockers (under the body, not the outside) and I’m trying to figure out how to get them to look the best for the longest amount of time with the least amount of work. Thinking cut off really rotten stuff and just coat the crap out of it with fluid film and hope for the best.
