I'm going to be installing the lip from below:
To go along with some roof flashing side skirt add-ons that I made for my VX.
(crummy cell pic)
I made the side skirts from vinyl covered roof flashing. I had a buddy with a 10' brake specifically for bending roof flashing.
I had them bent into a basic "J" shape to make attaching them to the OEM skirts easy.
I acquired some parts for my second version of a kammback as well, but I won't be able to work on that again until June
