side skirts and rear apron

[e30girl]

I have a 1990 325i convertible. I have the M tech factory air dam but I want the side skirts and the rear apron.. does anyone know where I can find this? Also i know that the side skirts need to be vert specific but do you know if the rear apron is vert. specific or can i buy any rear apron from a four door, coupe, etc?

Thanksss!!! :)
