It's such a shame they are original painted fenders with almost no other damage. The side cut was just folded down, but the top piece is missing.
The inside of the fender is curved on the bottom edge, what model would they be for?
17-25 Touring and Runabout rear fenders.
Not impossible to repair but you'd probably need a donor fender to cut a section out of.
Are they for sale?
You don't need donor fenders to repair those. Only need sheet metal and some basic tools.
Looks like they were cut to make a pick-up truck years ago.
