Replacement box sides for flareside
https://www.ford-trucks.com/forums/1...r-stuff-3.html
Why do you say they are to far gone? Got pictures of them so we can see?
I did not ever try to look for them as I did not have money to buy any, heck I did not have the money for the cross members!
Si I did the next best thing .... fixed them!
If you look the fenders cover most of the area that rust out so it does not need to look pretty and to make the lip is not hard.
As you can see I made cardboard templets from what I had left to use on flat stock to make new lips that I welded to the side panels.
Note drill the square holes in them before welding to the side panels.
We can help on how to fix just about anything even metal ribbed flare side floors
