Almost every Z in show competitions in the US aren't even fender kits... in fact they are customly done. What most do is cut the fender at an upward and out going shape (like lines kids draw on suns in kindergarten). Then they by hand bend them out & shape them with fiberglass. It is actually very easy, measuring & praying come a lot into play. The next Z project I do will get this treatment, By the way did this twice already. Now let's see...... $900 + shipping + labor + paint + 2-3 weeks waiting VS Fiberglass cost (cheap) + a 12 pack. Choose wisely
