Just an observation from the e-bay pics---they do not appear to have the compound shape needed to fit the car correctly. The bottom lip gets smaller at each end as well as the top of the rocker under the door, front fender and quarter panel. The bottom ends have a radius that roles into the bottom lip---not squared off. No drain divots in the bottom.
You should be able to see the differences with these pictures. I am not trying to poke at someone's work, these are just observations from the pictures supplied on ebay.
