Precision bent to fit right without a big fight. These are not same lines you buy from the other guys. These are steel and need to be as the fuel block is suspended on the driver's side. Line with fittings also in shop. If you are not going for the original look, the 64-65 lines fit and work perfectly as carbs are spaced same and fuel inlets in same location. Of course, the new lines are not rusty like in the picture.
