The wings that you have in the picture look like the lower section for the HD 70 series i.e. hzj bj etc.. I hope you haven't bought them Jimmy as they are longer and aren't a direct fit. Indeed the front wings are very hard to find!
There's two types of repair panels for the rear Ben. I found that the ones in black are much better than the light grey ones... as the light grey are very poor on the profile lines.
Hope the info is helpfull
