No they aren't too bad, I think replacing the bottom section along it's length will be a good repair that is strong and invisible. I don't think there is a real need to get into the massive task of replacing the rocker in it's entirety, but I don't want to do numerous patch repairs either.
I think on the whole I have gotten away fairly lightly with body repairs compared to what some of you guys are having to deal with. I paid quite a bit for this car at auction though, being led to believe it was rust free and it clearly wasn't....Still, ultimate responsibility lies with me, I should know better!
Meyer I think all cars have water traps and weak spots somewhere, Corvettes suffer in pretty much the same areas all the time. I can't imagine they were ever built to last 50 years or more so I guess they aren't doing too badly. I'll paint inside the rockers before I close them up, and after as best I can. I'll also inject all the box sections with a rust preventative to protect what I can as best I can.
Rob so far I have gotten most of the repair panels from Mercedes even though some have been repro as they weren't available OE, the only parts I have been very unhappy with are the floors under the rear parcel shelf, they are pretty bad but everything else looks like it is well made. I got the rear frame rails and seat members from K and K, the rear frame rails look nice although not perfect, the seat members are quite different and I will only use sections of them.
Better that than not being able to get anything though.
