I found this while doing some research on a Beemer for my mom. It tells you how to get an HID kit directly from a Ford dealer for $400. Then it gives you instructions on how to install them into E36 headlights. http://www.uucmotorwerks.com/html_te...ps/e36_hid.htm
It's in Adobe, go to page 4 for the dealer who offers this discounted price.
