The panels I looked at were pretty crude. I made my own lower 1/4s. My doors & fenders were good but making the bottoms would be pretty easy if you can find someone with a sheet metal brake. If the hood's rough I would replace it. 63 & 64 plymoth hoods are the same and not hard to find. Plenty of glass hoods as well. If you would like to see my 1/4 repairs search under user name dvw with patch panels in subject over the last 2 years. Sorry I don't know how to post them from the archives. It wasn't that hard. They were my 1st time.
Good luck.
Doug
