I have a decent fender pan from a '77 John Deere 312 that I am no long going to use. With a bit of straightening and some crack repair you would have a decent pan for a worker or a bit of additional work for a show machine. I have stripped most of the paint with a wire wheel as you can see in the pics.
According to JDParts the original part number is M48272 and it has been superseded by AM105025 which is shared with the 314s.
