Unless you have a 100% rustfree 1/4's that have never had any work done to them, I think you'll find that all the reproductions and even NOS ones will give you fitment issues. It's not usually the trim, it's the 1/4's.

Personally, for the customer's cars that I've worked on, all which have had major 1/4 work...I prefer the cheaper ones available through DALE'S CUDA SHOP They are quite a bit thinner then originals but allow you to work them over a bit to fit the car better.

Generally the area of body colour next to the tire should be covered unless the 1/4 panels are aftermarket and were never trimmed properly.
