I spent the entire day on the same parts as yesterday, I've found quite a few ill fitting parts in my kit so far but I think these take the cake. Lots of holes to open to the correct size, then when clecoed together there is misalignment of up to 4mm, flanges don't line up & holes miss each other by up to a full diameter. This is fairly heavy gauge material that is not readily manipulated. I'll be at the factory in a couple of weeks, I'm tempted to take these parts with me to get expert assistance.
