I have what appears to be a typical problem on an older Stang.
After forty some years of battery leaks and so forth my battery tray is toast but so is the fender apron under it.
I saw an article on Mustang monthly where they got the new metal but cut out just the rusted part and then put in a patch to match the cut out.
I am assuming a second option would be to replace the entire apron.
Which would be the better way to go?
Also, what would be involved in trying to replace the entire apron instead of just patching the rusted out area?
