I started detailing the Z today before I put her away for the winter and noticed a decent amount of rust on the rear sections of my rocker panels. I'm not sure how deep the rust is but I'm worried that once I start chipping away at it it's going to be more than I expected. Does anybody make replacement rocker panels? I know courtesyparts used to have oem replacements but those are long gone. Or am I stuck cutting some off of a parts car?
