Ace the process that you take measurements and divide and get an exact replica is the ideal case. However if you read Art's statement above the reality comes into play and its not just that simple. Think of it as connecting the dots. Somebody takes measurements and pictures and hand them to somebody else. That info is handed to somebody else and then they create the dots. A third person is handed the page with the dots and told to draw the picture. If they have no clue or only a general idea then that affects what they end up drawing. BOttom line. Kits sre going to end up with flaws. Everybody needs to deal with that in their own way. Ignore it, fix it, not buy it at all are all possible solutions. Endlessly discussing this is a futile endeavor.
