Everyone has a different standard for what is acceptable or not. I'll just add this. NOTHING made is an exact duplicate of original Cuda wheel lip moldings, further more, nothing fits the same (be it good bad or otherwise). That being said, it's the biggest reason mint NOS sets bring big bucks (how big? $1,200-$1,800.00 last time I saw a couple sets sell). Something to seriously consider If you are doing a top shelf OE style resto, or doing a big bucks car like a Hemi or 6 pack car.
In my experience the Metro moldings are my current choice or vendors if you decide to go with reproductions, they can be made to fit, but they will usually require some tweaking and screw hole adjustment to do so.
