Replacing corner bed strips?

[rdwhite01]

I'm am taking my pickup bed apart in preperation for paint and new wood on my 1957 short bed pickup. In the process I discovered my corner bed rails are not in the best of shape and need to be replaced. While I don't want to replace the whole bed side, I am unsure if trying to remove and replace the welded corner bed strips is worth the effort? Has anyone suscessfullly removed and replaced these welded corner strips and still ended up with a great looking pickup bed? If you have accomplished this task, what is the best method and what are the pitfall I can run into on this job.

Thanks for any help.
