This is a very good pic of what we are supposed to be seeing on the 64-5 lower quarters. The replacements fit good,but they do not have the compound curves of oem. If you look at the curved lower body line it appears that the lower quarter is straight,but it actually has a gradual curve that is also curved back out at the lower rear of the wheel well trim. This piece is difficult to find in decent used condition, so many are installing the aftermarket in pieces or making it fit otherwise. I have seen many rust-free advertised 64-5 cars with body lines that are just plain wrong from ten feet away. I?m not trying to be a perfectionist(synonymous with Chuck)....lol,but be aware of what it should look like on a proper repair.
