This illustrates what I said. You get a certain truck with a load of new sheet metal parts and it all fits well. Then you get a certain other truck with a load of parts and they "don't fit". So if there are many that do fit and some that don't fit, with all parts off the same dies, then it's the truck or user or parts got tweaked in shipping and handling. We do not know if we own a truck that has been misaligned. Many times when you restore a truck you find all kinds of "repairs" you didn't see before stripping it down. All they can do is build parts that match original drawings or that have been digitized from an N.O.S. example. If you don't trust them, use donor parts. If your truck is a tweaker and/or the donor part is a tweaker, it won't fit nice either. Sometimes you need to make it fit. It ain't no thing but a chicken wing.
China, like Japan have greatly improved manufacturing abilities/quality.
