[Merv and Sharon]

I am trying to decide on the type of fender spats (for the leading face of the rear wheel arches) to use on a Harrison Cobra. I have seen the stainless steel ones and some ally ones. Some seem too short, but they all are a bit 'bling', at least to my eye, at this stage. My car will be black. Have also looked at the the 3M clear adhesive material. Could be OK. One that caught my eye was the leather/vinyl, clip on type. I am not entirely sure how that attach to the inner part of the arch but they do look the goods.

Has anyone had experience with these? Do they work? Do they flap around? Where would one get them or a template for them? Have tried to attach a photo.
