OER Body Panels ... any good

I'm trying to gather parts for my '70 Duster build and as it turns out, AMD is pretty much cleaned out of a lot of their stock which has me looking at alternatives such as Goodmark and most recently OER.

A guy somewhat local to me as a set of OER quarter skins for what I consider to be a great price but I'm not familiar with the quality of this brand.

Does anyone here have experience with OER panels and their quality and fitment?
