Good morning!
Long story short, I was able to fix mine with using aftermarket front fenders and cutting them and piecing them together.
Short of that, I do know that there is an aftermarket (or was) side you could get, but when I saw the quality of it, the stamping wasn't a stamping, it was a hammering over a buck.
So, that is an option as well I guess... make your own wooden buck and hammer over and make a new part... or make a 2 piece and put it in a press. Not sure what tools/options you have.
Good luck... it isn't a ton of fun either way.
This shows more of the pictures of cutting up the front fender and fitting.
