markdoane,
I don't think that the trailer skin has been modified, just the plastic material added when the original trim was removed. I'm cudious, the bottom right photo in your post: is that the original trim? That's what I think I'm looking for.
The overall shape of our wheel well is what I understand a California trailer wheel well looks like, the ohio should be more arched -- without the peak?
Also, thanks for the link, the closest trim looks to be the first one on the page?
Cap G51SL 1/16"
