Need input on quarter skins please

Im needing new quater skins for my 71 duster and from what research Ive done there is only one type currently on the market.It seems everything currently available is stamped off the same dies in Taiwan and Im just wondering who has used these panels and how they fit.Im concearned about them being way off on body lines ect.,if anyone has any experience with them I would really appreciate it,thanks.
