Or, find a good HX body shell to replace the rusty one..... Probably as hard as finding a good mostly rust free Sandman.

I ended up finding a good mostly rust free HJ Sandman van before a good HX body to replace the rusty one on my Absinth yellow HX Sandman.... I just sold the very rusty HX Sandman a week or so ago for $1500 after stripping it of most the good bits as I still hadn't found a good replacement shell.
