CJ jeep bed repair

I’m looking for someone who may have pieces of rear bed panel that they are
willing to part with to make repair from what looks to be fertilizer spill. Or can you do the repairs yourself?  In particular the left rear 10″ between the rear floor support/rollbar brace and tailgate end support. Bed is in good condition otherwise and do not want to replace the entire bed. Any help or advice would be most appreciated.

You can get replacement panels at http://www.funjeeparts.com or http://www.classicent.com/jeep.php

I have a picture of the bed.

Thanks for the pic, more or less I could use any section to make repairs needed as the profile of the ribs should align. I feel that finding exactly the same area that is rotted out is slim due to being welded into the tailgate support. A much larger area would have to be cut out to get to weldable metal. I have used replacement pieces (corners, floor supports, and foot boards) from Classicent before however the ribs on the bed panel have a different profile than OEM.

Very interested and will cover cost of goods and your service, within reason of course.
