openers

ok guys i seen these a while back when i a salvage yard. carnt rememebr wehat they where on but it was definatly a coupe. i remember them as i thought it was quite a good but lazy idea. basicly they where rods which extented thus opening the window anyone know what series and model these came on?

hi ive just been looking at a e36 that has the electric pop out windows, my car has the manual pop out windows i was wondering if any1 knows how to and how hard it is to convert them to electric if possible?? cheers:)
